| In the Linux kernel, the following vulnerability has been resolved:
USB: serial: digi_acceleport: fix hard lockup on disconnect
If submitting the OOB write urb fails persistently (e.g if the device is
being disconnected) the driver would loop indefinitely with interrupts
disabled.
Check for urb submission errors when sending OOB commands to avoid
hanging if, for example, open(), set_termios() or close() races with a
physical disconnect.
This is issue was flagged by Sashiko when reviewing an unrelated change
to the driver. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: composite: fix dead empty check in the USB_DT_OTG handler
The OTG branch of composite_setup() falls back to the first
configuration when none is selected:
if (cdev->config)
config = cdev->config;
else
config = list_first_entry(&cdev->configs,
struct usb_configuration, list);
if (!config)
goto done;
...
memcpy(req->buf, config->descriptors[0], value);
list_first_entry() never returns NULL. On an empty list it returns
container_of() of the list head. So the "if (!config)" check is dead.
When cdev->configs is empty, config points at the head inside struct
usb_composite_dev. config->descriptors[0] reads whatever sits at that
offset. The memcpy copies up to w_length bytes of it into the response
buffer.
cdev->configs can be empty in two cases. One is a teardown race on
gadget unbind with a control transfer in flight. The other is a driver
that sets is_otg before it adds a config. A reproducer that holds
cdev->configs empty triggers a KASAN fault in this branch.
Use list_first_entry_or_null() so the existing check does its job. |
| A flaw was found in the first-broker-login flow of the Keycloak identity management service. When a user links a social identity provider account to their local account, the verification proof generated is not strictly bound to the specific upstream identity being verified. This allows an attacker with a different account on the same social provider to intercept the process and link their own account to the victim's local profile, gaining unauthorized access. |
| The MasterStudy LMS WordPress Plugin WordPress plugin before 3.7.46 does not properly verify authorization when retrieving order line-item data, allowing any authenticated user including Subscribers to read other instructors' course sales records by supplying another user's identifier. |
| The MasterStudy LMS WordPress Plugin WordPress plugin before 3.7.46 does not properly verify ownership of quiz question identifiers, allowing users with instructor access to read other instructors' quiz questions, including the correct answers and explanations. |
| The MasterStudy LMS WordPress Plugin WordPress plugin before 3.7.46 does not properly verify ownership of a curriculum object before acting on it, allowing authenticated users with the instructor role to delete or modify curriculum sections and materials belonging to courses owned by other instructors. |
| Jenkins Microsoft Entra ID (previously Azure AD) Plugin 710.v0b_ff8e9cc2d2 and earlier grants Entra group permissions using both the group's unique object ID and its display name, allowing attackers who can create an Entra group with a colliding display name to gain the permissions configured for a privileged group. |
| In the Linux kernel, the following vulnerability has been resolved:
netfs: Fix missing barriers when accessing stream->subrequests locklessly
The list of subrequests attached to stream->subrequests is accessed without
locks by netfs_collect_read_results() and netfs_collect_write_results(),
and then they access subreq->flags without taking a barrier after getting
the subreq pointer from the list. Relatedly, the functions that build the
list don't use any sort of write barrier when constructing the list to make
sure that the NETFS_SREQ_IN_PROGRESS flag is perceived to be set first if
no lock is taken.
Fix this by:
(1) Add a new list_add_tail_release() function that uses a release barrier
to set the pointer to the new member of the list.
(2) Add a new list_first_entry_or_null_acquire() function that uses an
acquire barrier to read the pointer to the first member in a list (or
return NULL).
(3) Use list_add_tail_release() when adding a subreq to ->subrequests.
(4) Use list_first_entry_or_null_acquire() when initially accessing the
front of the list (when an item is removed, the pointer to the new
front iterm is obtained under the same lock). |
| claude-skill-antivirus fails to analyze executable files when scanning local skill directories, reading only SKILL.md while ignoring Python source, bytecode, and other artifacts in the scripts directory. Attackers can distribute skills with malicious code in non-manifest files that receive a SAFE verdict with 100/100 trust score despite containing unanalyzed executable payloads. |
| agentverus-scanner fails to analyze compiled Python bytecode files in companion code directories, allowing attackers to bypass security scanning by shipping malicious __pycache__ entries alongside benign source files. Attackers can execute arbitrary Python bytecode on import while the scanner reports a CERTIFIED verdict with high trust scores in both static and semantic analysis modes. |
| HTTPX2 is a next generation HTTP client for Python. From 2.5.0 until 2.10.0, the HTTPX2 Server-Sent Events parser in src/httpx2/httpx2/_sse.py repeatedly copies and rescans buffered text in _SSELineDecoder.decode() when an attacker-controlled or compromised SSE endpoint splits one unterminated line across many response chunks. The behavior affects httpx2.Client.sse() and httpx2.AsyncClient.sse(), and the total processing work grows quadratically with the line length, allowing a crafted stream to consume excessive CPU and block a synchronous worker or asynchronous event loop. This issue is fixed in version 2.10.0. |
| PREVAIL is a Polynomial-Runtime EBPF Verifier using an Abstract Interpretation Layer. Prior to version 0.2.4, in the Prevail eBPF verifier, EbpfTransformer::add() silently skips offset-variable updates when the destination register carries a non-singleton typeset (two or more simultaneously possible pointer types). Subsequent bounds checks use the stale offset and accept out-of-bounds memory accesses, so a crafted BPF program passes verification even though it would corrupt memory at runtime. This issue has been patched in version 0.2.4. |
| PREVAIL is a Polynomial-Runtime EBPF Verifier using an Abstract Interpretation Layer. Prior to version 0.2.4, the prevail eBPF verifier accepts ALU32 ADD and SUB instructions that operate on pointer-typed registers without checking the is64 flag. Because ALU32 arithmetic zero-extends the 32-bit result, the upper half of any pointer is silently destroyed at runtime, yet prevail marks the program as verified safe. Any caller that can submit an eBPF program for verification — including unprivileged users on kernels that permit BPF program loading — can produce a program that passes verification but faults or misbehaves at runtime. This issue has been patched in version 0.2.4. |
| In the Linux kernel, the following vulnerability has been resolved:
netfs: Fix missing locking around retry adding new subreqs
Fix netfs_retry_read_subrequests() and netfs_retry_write_stream() to take
the appropriate lock when adding extra subrequests into
stream->subrequests. |
| Authorization bypass through user-controlled key issue exists in ShizenBox2 (edge-app). If exploited, an attacker who can log in to the product may change the other user's password. |
| XG VisionTerminal and XG-X VisionTerminal provided by Keyence Corporation improperly restrict XML external entity references. If a user opens a specially crafted setting file, the sensitive information stored in the system where XG VisionTerminal or XG-X VisionTerminal is installed may be disclosed. |
| In Eclipse Arrowhead versions from 5.0.0 to 5.2.1 the management-authorization gate that protects every /…/mgmt/… REST endpoint decides whether to apply its check by calling request.getRequestURL().toString().contains("/mgmt/"). Tomcat returns getRequestURL() un-decoded, while Spring MVC's DispatcherServlet routes on the decoded path. Requesting /serviceregistry/%6Dgmt/systems (%6D == m) therefore fails the substring check — the filter falls through without authorising — yet is decoded to /serviceregistry/mgmt/systems and dispatched to the management controller. Spring Security's StrictHttpFirewall (active via spring-boot-starter-security in arrowhead-common) only rejects encoded / \ . % ; and null bytes, so percent-encoded ASCII letters pass through. Any authenticated system — regardless of privilege — can reach every management operation, including POST /authentication/mgmt/identities which creates new sysop accounts, yielding full administrative takeover of the local cloud. |
| vhr fails to validate user authorization in the PUT /hr/info endpoint, allowing authenticated users to modify arbitrary HR profiles by supplying any profile ID in the request body. Attackers can overwrite other users' names, addresses, and disable accounts including administrators to cause denial of service. |
