| In the Linux kernel, the following vulnerability has been resolved:
ethtool: module: avoid leaking a netdev ref on module flash errors
module_flash_fw_schedule() is missing undo for setting
the "in_progress" flag and taking the netdev reference.
Delay taking these, the device can't disappear while
we are holding rtnl_lock. |
| Pydantic AI is a Python agent framework for building applications and workflows with Generative AI. From 2.10.0 until 2.53.0, streamed requests made through ConcurrencyLimitedModel or limit_model_concurrency can retain shared concurrency slots because anyio.CapacityLimiter associates an acquired slot with the borrowing task while streaming cleanup can run in a different task. Early stream termination, cancellation, consumer exceptions, or complete stream_text() consumption with debounce_by=0.1 can therefore leave capacity occupied, eventually preventing later requests that share the long-lived limiter from proceeding and causing a denial of service. Agent-level max_concurrency and non-streaming model requests are not affected. This issue is fixed in version 2.53.0. |
| IBM Power Systems Firmware FW1110.00 through FW1110.31, FW1120.00 through FW1120.01, and FW1060.00 through FW1060.81 could allow a remote authenticated attacker to cause a denial of service by exhausting connection resources due to improper resource management. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: cleanup arsta in ath11k_mac_peer_cleanup_all()
When mac80211 removes a sta, it calls .sta_state() which in turn calls
ath11k_mac_station_remove(). In that function we clean up both peers &
arsta related resources.
But when the firmware crashes, ath11k calls ieee80211_restart_hw(), which
assumes that all driver related resources are cleaned up beforehand. This
cleanup is supposedly done by ath11k_mac_peer_cleanup_all() but does not
in fact free arsta->rx_stats / tx_stats.
Extract the arsta cleanup from ath11k_mac_station_remove() into a
new ath11k_mac_station_cleanup() and call it from both there and
ath11k_mac_peer_cleanup_all().
This should handle kmemleaks reports like:

| In the Linux kernel, the following vulnerability has been resolved:
drm: Fix drm_pending_vblank_event leak in error path for out_fence_ptr
When an out_fence_ptr is provided but DRM_MODE_PAGE_FLIP_EVENT is not
set, a drm_pending_vblank_event will be allocated. If later, there is an
allocation failure or another failure at setup_out_fence(), that event
will not have base.fence set and it will not be released at
complete_signaling().
Release the event and set crtc_state->event to NULL just like in the
DRM_MODE_PAGE_FLIP_EVENT case when there is a failure at
drm_event_reserve_init(). That is, prepare_signaling() releases the
event and there is nothing to be done at complete_signaling(). Use
drm_event_cancel_free() as that will also undo drm_event_reserve_init()
in case it has been called. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: mesh: reset the CSA state when leaving
ifmsh->csa is allocated in ieee80211_mesh_csa_beacon() and only freed
in ieee80211_mesh_finish_csa(), i.e. when the channel switch completes.
Leaving the mesh while a switch is still pending therefore leaks it.
Additionally, ifmsh->csa_role and ifmsh->chsw_ttl have their state leak
in this case, so things can get mixed up in addition to the memory
leak.
Refactor the reset and call it in ieee80211_stop_mesh() to fix it all. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_nat: unregister and release hooks on error
If nf_hook_entries_insert_raw() fails, the NAT hooks get never released,
resulting in a memleak.
Postpone setting nat_proto_net->nat_hook_ops when the hooks are
registered to simplify the error path to decide whether the nat hooks
need unwinding. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: virt_wifi: free skb when disconnected
When the simulated link is disconnected, virt_wifi_start_xmit() returns
NET_XMIT_DROP without freeing the skb. dev_hard_start_xmit() treats this
return value as consumed, so every packet sent while disconnected leaks its
skb.
Free the skb before returning the drop status. |
| OpenPrinting CUPS through 2.4.20 contains a resource-exhaustion vulnerability in the submission-timeout handling of cupsdCheckJobs(). The scheduler suppresses timeout processing for all pending jobs whenever any client connection has an in-flight Send-Document operation, without matching that connection to the job being examined. A client allowed to reach the IPP service can hold an incomplete HTTP request containing parsed Send-Document headers before operation authorization, preventing unrelated incomplete jobs from expiring. Where Create-Job submission is allowed, incomplete jobs can accumulate until MaxJobs is exhausted and further legitimate print submissions are rejected. The suppression ends when the held connection closes. |
| A missing release of resources in the illumos name service cache daemon (nscd) allows a local user to exhaust kernel memory. The nscd door server procedure, switcher() in usr/src/cmd/nscd/nscd_frontend.c, does not close file descriptors that are passed with a door call but not used by the request, and the main nscd door at /var/run/name_service_door accepts passed descriptors from any user in its zone. Because nscd also runs with an unlimited file descriptor limit, an unprivileged local user, including one in a non-global zone, can repeatedly pass a descriptor to its zone's nscd in a door_call() loop, causing the file descriptor table of nscd to grow without bound in kernel memory. This causes a denial of service of nscd and can render processes in all zones on the host unresponsive. The flaw has existed since 2006 (illumos-gate commit cb5caa98), and affects any illumos distribution prior to illumos-gate commit af810a72. |
| In the Linux kernel, the following vulnerability has been resolved:
memstick: ms_block: destroy io_queue workqueue on removal
msb_init_disk() creates the per-card ordered workqueue msb->io_queue with
alloc_ordered_workqueue(). It is torn down with destroy_workqueue() only
on the init error path; msb_remove() never destroys it. msb_stop() merely
flushes the queue, and neither msb_data_clear() nor put_disk() free it. As
a result every card insert/remove cycle leaks the workqueue and its
kworker, exhausting kernel memory over repeated cycles.
Destroy the workqueue in msb_remove() after the disk has been removed and
the queue drained. |
| In the Linux kernel, the following vulnerability has been resolved:
mmc: sdio_uart: fix xmit_fifo leak when the port table is full
sdio_uart_add_port() allocates the transmit fifo before claiming a
slot in sdio_uart_table[]. When all UART_NR slots are taken, it
returns -EBUSY with the fifo still allocated, but the probe error
path only kfree()s the port, leaking the transmit fifo.
Free the fifo in the failure path of sdio_uart_add_port() itself so
the function retains nothing on error. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/vma: correctly unaccount on mmap_prepare() failure
__mmap_setup() accounts memory for relevant mappings via:
security_vm_enough_memory_mm()
-> __vm_enough_memory()
-> vm_acct_memory()
If __mmap_setup() fails, this indicates that this accounting did not take
place, and thus it's appropriate for __mmap_region() to jump to
abort_munmap.
However if call_mmap_prepare() fails, it also jumps there and any accounted
memory is not correctly unaccounted.
Fix this by handling each error separately. |
| This CVE ID has been rejected as a duplicate. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix rmmio iounmap skipped on device removal
amdgpu_pci_remove() calls drm_dev_unplug() before fini_sw(), so
drm_dev_enter() is already false there and the iounmap() guarded by it
is skipped. This .remove path runs on both hot-unplug and plain rmmod,
so the register BAR ioremap mapping leaks one instance per unload.
Unmap rmmio unconditionally (guard only on non-NULL) and drop the now
unused idx.

| An issue was discovered in the Linux kernel 4.18 through 5.6.11 when unprivileged user namespaces are allowed. A user can create their own PID namespace, and mount a FUSE filesystem. Upon interaction with this FUSE filesystem, if the userspace component is terminated via a kill of the PID namespace's pid 1, it will result in a hung task, and resources being permanently locked up until system reboot. This can result in resource exhaustion. |
| mwifiex_tm_cmd in drivers/net/wireless/marvell/mwifiex/cfg80211.c in the Linux kernel before 5.1.6 has some error-handling cases that did not free allocated hostcmd memory, aka CID-003b686ace82. This will cause a memory leak and denial of service. |
| IEEE C37.118 Synchrophasor protocol dissector memory leak in 4.6.0 to 4.6.8 and 4.4.0 to 4.4.18 allows denial of service |
| improper handling of exceptional conditions, Missing release of resource after effective lifetime vulnerability in Apache Thrift java bindings.
This issue affects Apache Thrift: before 0.25.0.
Users are recommended to upgrade to version 0.25.0, which fixes the issue. |
