| In the Linux kernel, the following vulnerability has been resolved:
sctp: fix soft lockup from unpadded ASCONF-ACK parameter iteration
sctp_verify_asconf() walks ASCONF-ACK parameters with
sctp_walk_params(), which advances by SCTP_PAD4(length), while the
consumer sctp_get_asconf_response() iterates the same parameters
advancing by the raw length, without padding. A single odd-length
parameter desynchronises the two walks and makes the consumer
interpret attacker-controlled bytes at a misaligned offset.
When those bytes yield a length of zero, the while loop over
asconf_ack_len makes no progress, spinning forever in softirq
context, and the watchdog reports a soft lockup. All reads stay
within the received skb, so the lockup is a pure remote denial of
service. A remote peer can trigger it with a crafted ASCONF-ACK on
an ADD-IP enabled association with an outstanding ASCONF (RFC 5061
section 4.1.2 requires the chunk to be authenticated, but the
predefined empty key id 0 allows the peer to compute the same
association HMAC from publicly exchanged parameters, so the gate
does not help).
The SCTP_PARAM_ERR_CAUSE case of sctp_verify_asconf() also performs
no length check, letting a parameter without a complete error
header reach the consumer, which reads errhdr.cause past the end of
the parameter, an out-of-bounds read.
Reject SCTP_PARAM_ERR_CAUSE parameters shorter than
sizeof(struct sctp_addip_param) + sizeof(struct sctp_errhdr) at the
verifier, and advance the consumer iterator with the same padding
rule as the verifier to keep the two walks in lockstep. The verifier
change guarantees a complete error header in every ERR_CAUSE
parameter the consumer can see, so the consumer's asconf_ack_len
check is dropped and it returns err_param->cause directly. The
consumer padding fix is still required because odd lengths remain
valid for SCTP_PARAM_ERR_CAUSE per RFC 5061.
The issue was found by ZeroHive, a vulnerability hunting agent at
Tencent Yunding Lab. |
| In the Linux kernel, the following vulnerability has been resolved:
smb/client: validate new EOF for zero range
When FALLOC_FL_ZERO_RANGE is used without FALLOC_FL_KEEP_SIZE,
smb3_zero_range() may extend EOF without checking RLIMIT_FSIZE, allowing
the file to grow beyond the caller's file-size limit.
Fix this by calling inode_newsize_ok() before sending the zero-range
request when the operation would extend EOF.
Reproducer, using a file on a CIFS mount:
bash -c '
FILE=/mnt/cifs/repro
trap "" SIGXFSZ
ulimit -f 3072
truncate -s 2M "$FILE"
fallocate --zero-range -o 0 -l 4M "$FILE"
echo "fallocate rc=$?"
stat -c "file size=%s" "$FILE"
'
Before this change, the operation succeeds despite the 3 MiB limit:
fallocate rc=0
file size=4194304
After this change, fallocate fails and leaves the file at 2 MiB. |
| In the Linux kernel, the following vulnerability has been resolved:
sctp: fix a TOCTOU race in SCTP_CMD_TIMER_START
The SCTP_CMD_TIMER_START handler checks timer_pending() before calling
timer_reduce(). The timer can expire and detach between these operations,
causing timer_reduce() to rearm the timer without taking the association
reference required for the newly armed timer.
The timer callback later unconditionally drops its association reference,
which can leave the association reference count unbalanced and result in
use-after-free during association teardown.
Use the return value of timer_reduce() to determine whether the timer was
actually armed. Take the association reference only when timer_reduce()
successfully starts a new timer, closing the race between checking the
timer state and rearming it.
This issue was reported by Nico Yip (@_cyeaa_) working with TrendAI Zero
Day Initiative. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: leave HasEA flag untouched on setxattr failure
In ntfs_set_ea(), the exit path unconditionally updates the HasEA
flag based on ea_info_qsize. When an error occurs before
ea_info_qsize is updated, NInoClearHasEA() hides existing on-disk
EAs until the inode is evicted.
Only update the flag on success. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/arm-smmu-v3: Manage teardown with devm
arm_smmu_device_remove() manually frees the IOPF queue, destroys the
vmid_map and disables the device, while the IRQs and queues are devm
managed. devm unwinds only after remove() returns, so the cleanup runs
in the wrong order. The IOPF queue is freed before the event-queue IRQ
whose handler uses it.
Manage all of it with devm so the unwind order is correct. Free the IOPF
queue and vmid_map via devm actions, and disable the device from one
registered after arm_smmu_device_reset().
This is also a prerequisite for fixing a Tegra241 CMDQV CMD_SYNC
use-after-free in the subsequent patch. |
| In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: Zero rpc_gss_wire_cred at svcauth_gss_decode_credbody() entry
svcauth_gss_decode_credbody() writes the caller's
rpc_gss_wire_cred field by field and assigns gc_ctx.len only on
the success tail. The caller storage is svcdata->clcred, which
lives in the per-svc_rqst gss_svc_data and is reused across
requests. Early decode failures leave partially decoded state
mixed with residue from the prior request.
The trailing body_len tightness check is the sharpest case:
xdr_stream_decode_opaque_inline() has already written gc_ctx.data
with a borrowed inline pointer into the current request's XDR
pages, but gc_ctx.len retains its prior value. Once the request
pages are released the pooled clcred carries a dangling pointer
paired with a stale length.
Zero the caller's rpc_gss_wire_cred at function entry so that
every early-return path leaves a deterministic all-zero cred.
On the trailing tightness-check path, gc_ctx.len is now zero
instead of stale, which neuters length-driven consumers such as
gss_svc_searchbyctx() that would otherwise walk the dangling
data pointer. |
| In the Linux kernel, the following vulnerability has been resolved:
nfsd: initialize DRC hash table before registering shrinker
shrinker_register() precedes the INIT_LIST_HEAD loop and the
drc_hashsize store. On weakly-ordered architectures (arm64, ppc),
a shrinker scan can observe drc_hashsize before the bucket list
heads are initialized, causing a NULL deref in the DRC shrinker
callback.
Move bucket initialization and the drc_hashsize store before
shrinker_register() so the hash table is fully initialized before
it becomes visible to the shrinker. |
| In the Linux kernel, the following vulnerability has been resolved:
nfsd: guard nfsd_serv deref in nfsd_file_net_dispose
nfsd_file_net_dispose() is the consumer side of l->freeme: the nfsd
service thread loop calls it to drain entries that the filecache
garbage collector and shrinker append via
nfsd_file_dispose_list_delayed(). During per-net teardown,
nn->nfsd_serv is cleared before the filecache laundrette is shut
down, so the service thread can still run a dispose pass that finds
more than eight entries on l->freeme and dereferences a NULL
svc_serv:
nfsd service thread loop
nfsd_file_net_dispose(nn)
if (!list_empty(&l->freeme)) {
...
svc_wake_up(nn->nfsd_serv); /* nn->nfsd_serv == NULL */
}
The sibling helper nfsd_file_dispose_list_delayed() already documents
this ordering and caches nn->nfsd_serv into a local before testing it
for NULL. nfsd_file_net_dispose() was introduced with the same raw
svc_wake_up(nn->nfsd_serv) call and never picked up the guard.
Fix by loading nn->nfsd_serv into a local svc_serv pointer and only
calling svc_wake_up() when it is non-NULL, matching the pattern in
nfsd_file_dispose_list_delayed(). |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_tcm: fix deadlock in usbg_make_tpg()
usbg_make_tpg() held dep_lock while calling
configfs_depend_item_unlocked(), which acquires the configfs root
inode lock when operating across subsystems. This creates a circular
lock dependency with configfs_rmdir():
dep_lock -> configfs root inode lock -> su_mutex -> dep_lock
In usbg_make_tpg(), dep_lock only serialized the read of opts->ready,
which is a monotonic flag that transitions from false to true exactly
once (in tcm_set_name()) and never reverts. Remove dep_lock from
usbg_make_tpg() entirely and use READ_ONCE/WRITE_ONCE to access
opts->ready locklessly instead. |
| LibRaw 0.22.0 contains an incorrect numeric conversion vulnerability in LibRaw::parse_tiff_ifd() when processing TIFF tag 0x00fe (NewSubfileType). A specially crafted RAW, TIFF, or DNG file can supply an attacker-controlled NewSubfileType value outside the range of a signed int. The parser converts this value and narrows it to int without performing range validation. This out-of-range conversion triggers undefined behavior, resulting in process termination and denial of service. |
| Improper handling of compressed data in the shared GZIP decompressor used for AMQP 0-8/0-9/0-9-1 and AMQP 0-10 message delivery, message conversion and HTTP management JSON rendering allows authenticated message producers to exhaust memory and disrupt broker availability via processing without a decompressed-output limit.
This issue affects Apache Qpid Broker-J: through 10.1.0.
Users are recommended to upgrade to version 10.1.1, which fixes the issue. |
| The GeoDirectory – WP Business Directory Plugin and Classified Listings Directory plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'business_hours' parameter in all versions up to, and including, 2.8.183 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is possible because the AJAX save handler validates only post authorship and a nonce with no additional capability check, allowing any subscriber-level user who owns a listing to exploit this vulnerability. |
| The Zero Spam for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Nested POST Array Keys via Contact Form 7 Integration in all versions up to, and including, 5.7.10 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload is delivered by submitting a Contact Form 7 request with a nested POST array key containing arbitrary HTML or JavaScript — PHP parses the field name into a nested array key, which is stored verbatim in the zerospam_log.submission_data column when Zero Spam flags the submission as spam due to the absence of the zerospam_david_walsh_key field. |
| The Repeater Fields for Elementor Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Repeater Field Value in all versions up to, and including, 2.2.7 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. |
| The Premium Packages – Sell Digital Products Securely plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'cart_items[][product_name]' Parameter in all versions up to, and including, 7.2.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The checkout REST route uses permission_callback set to __return_true and the invoice loader performs no order ownership check, meaning an unauthenticated attacker can both persist the payload and ensure it is renderable to any logged-in user who accesses the invoice. |
| The Online Scheduling and Appointment Booking System – Bookly plugin for WordPress is vulnerable to Authorization Bypass via PHP Type Juggling in all versions up to, and including, 28.2. This is due to the `postValidateCustomer()` function using a loose PHP inequality operator (`!=`) to compare the session-stored one-time verification code against the attacker-supplied `verification_code` parameter — a flaw that is further exposed by the booking AJAX controller registering all its methods as `wp_ajax_nopriv_` handlers and unconditionally overriding `csrfTokenValid()` to return true, leaving the endpoint both unauthenticated and CSRF-unprotected. This makes it possible for unauthenticated attackers to bypass the phone/email ownership verification step and overwrite the name, email, phone, and address fields of any arbitrary existing Bookly customer record, redirecting that customer's booking notifications to attacker-controlled contact details. The bypass is achievable because the `json_data` input channel decodes input via `json_decode()`, which preserves real PHP types and causes the `wp_kses` filter to leave non-string values such as the JSON boolean `true` untouched; submitting `true` as the `verification_code` satisfies the loose comparison against the session's non-zero integer code (generated by `mt_rand(100000, 999999)`), causing `true != <non-zero int>` to evaluate as `false` and the guard to be bypassed. |
| The WPForms – AI Form Builder for WordPress – Contact Forms, Payment Forms, Survey Form, Quiz & More plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via 'page_title' POST Parameter via {page_title} Smart Tag in all versions up to, and including, 2.0.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. This is only exploitable on forms whose admin-authored confirmation message places the {page_title} Smart Tag inside an HTML attribute context. |
| The Fancy Product Designer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'productTitle' in '_fpd_data' Order Item Meta in all versions up to, and including, 6.5.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The fpd_save_order AJAX action is registered for unauthenticated users via wp_ajax_nopriv_fpd_save_order with no nonce or capability check, and the strip_tags() sanitization applied at save time is bypassed by submitting JSON unicode escape sequences (e.g. \u003c, \u003e), which json_decode() silently converts back to literal angle brackets when the order is rendered in the admin view. |
| An attacker with access via network to the Regesta Smart HD-PLC of the provider Teldat (in this case, registration action is required) who has the vulnerable firmware version could inject
a specific payload via the parameter "cmdcookie" withing the /upgrade/index.html resulting in to a Cross-Site Scripting (XSS). This issue affects Regesta Smart HD-PLC - TLDPH16D2:
11.02.06.00.02 |
| The SSL Zen plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'uri' (and 'host') parameters in versions up to, and including, 4.7.42. The ssl_zen_messages::getMessages() function builds the 'token_missmatch' message using base64_decode(sanitize_text_field($_REQUEST['uri'])) and (optionally) base64_decode(sanitize_text_field($_REQUEST['host'])). sanitize_text_field() cannot strip HTML/JavaScript that is hidden inside a base64-encoded blob, and the resulting decoded raw HTML is echoed unescaped by showMessage() . This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a specially crafted link. |
