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-2026-68202

CVE-2026-68202 affects the Linux kernel’s ALSA sequencer. A race in queue timer cleanup allows an unprivileged local user with access to /dev/snd/seq to re-open a timer that has just been closed, leading to a use-after-free of the timer/queue object and a potential crash or, in theory, arbitrary ...

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...

PT-2026-69602

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the ALSA sequencer where a queue timer can be re-opened during the destruction process. When queue delete is called, it closes the queue timer and subsequently frees i...

CVE-2026-64479

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA sequencer. This vulnerability allows an unprivileged local user to trigger a heap information leak in the sndseqeventdup function. By reading from /dev/snd/seq, an attacker can obtain 4 bytes of uninitialized kernel hea...
