CVE-2026-12366

Zephyr's dynamic kernel-object disposal path unrefcheck in kernel/userspace/userspace.c frees an object's storage kfreedyn-data once its reference count reaches zero, after running a per-object-type cleanup. The cleanup switch handled only KOBJMSGQ and KOBJSTACK; there was no KOBJTIMER case. A...

CVE-2026-12366

Summary: CVE-2026-12366 in Zephyr describes a use-after-free in the dynamic object disposal path for kernels objects. When a user-thread holds the last permission on a timer (K_OBJ_TIMER) and frees it, the timer’s memory is released without cancelling its embedded _timeout node from the global _t...

CVE-2026-73561

Hub is a Node.js WebSocket server and client with added features. Prior to 0.2.16, every incoming unauthenticated WebSocket connection triggers loadDefaultConnectionEventListeners to call requestClientId, which calls rpc.send for the get-client-id action and pushes a request into RPC.requests. Th...

CVE-2026-68202

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture sequencer component. An unprivileged local user with access to the sound device can exploit a timing window during the cleanup of a queue timer. This allows the user to re-open a timer that has already been closed,...

CVE-2026-68233

A flaw was found in the drm/vc4 component of the Linux kernel. A logic error in the BO cache timer shutdown process allows the timer to be rearmed even after it has been destroyed. This can lead to work being queued again after teardown, potentially causing system instability or a denial of servi...

CVE-2026-68198

A flaw was found in the Linux kernel's ath6kl Wi-Fi driver. A use-after-free vulnerability exists within the aggrresetstate function. This occurs because a non-synchronous timer deletion allows a timer callback aggrtimeout to access memory that has already been freed, creating a race condition. A...

CVE-2026-68200

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA timer component. A lack of serialization in the userspace-driven timer utimer TRIGGER ioctl allows two threads to concurrently call sndtimerinterrupt. This race condition can lead to a use-after-free vulnerability, wher...

CVE-2026-68090

A flaw was found in the debugobjects component of the Linux kernel. A race condition can occur when an out-of-memory OOM situation happens concurrently with certain debug object operations. This can lead to a dysfunctional timer and a kernel warning, potentially causing system instability or a...

CVE-2026-68201

A flaw was found in the ALSA Advanced Linux Sound Architecture timer component of the Linux kernel. When a master timer instance is closed, it does not properly ensure that all associated slave timer callbacks have finished executing before detaching them. This oversight can lead to a...

Linux Distros Unpatched Vulnerability : CVE-2026-68201

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ALSA: timer: drain a slave's callback before its master detaches it sndtimercloselocked drains the closing instance's own in-flight callback IFLGCALLBACK before...

Linux Distros Unpatched Vulnerability : CVE-2026-68200

CVE-2026-68233

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Shut down BO cache timer before teardown The BO cache timer callback schedules timework, and timework can rearm the timer through vc4bocachefreeold. vc4bocachedestroy deletes the timer and then cancels the work, which do...

CVE-2026-68202

In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: close a re-opened queue timer in the destructor queuedelete closes the queue timer, then frees it. sndseqtimerclose clears q-timer-timeri. snduselocksync then drains borrowers, and sndseqtimerdelete frees q-timer. A...

CVE-2026-68198

In the Linux kernel, the following vulnerability has been resolved: wifi: ath6kl: fix use-after-free in aggrresetstate The aggrresetstate function uses timerdelete non-synchronous for the aggregation timer before proceeding to delete TID state and before the structure is freed by callers like...
