CVE-2026-74339

The CVE-2026-74339 entry describes a Linux kernel ALSA seq vulnerability in snd_seq_read where a queued variable-length event header could reveal a kernel address via data.ext.ptr, because the read path did not clear the temporary header pointer before copy_to_user. The fix involves clearing that...

CVE-2026-74261 ALSA: seq: avoid stale FIFO cells during resize

In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: avoid stale FIFO cells during resize sndseqfiforesize still needs to publish the replacement pool before it waits for FIFO users. A blocking sndseqread holds f-uselock while it sleeps, so concurrent senders must be abl...

CVE-2026-74261

CVE-2026-74261 — In the Linux kernel ALSA sequencer, a bug during fifo pool resize could leave stale cells and block pool teardown. The issue stems from snd_seq_fifo_resize() waiting for the replacement pool while a reader holds f->use_lock, and race conditions where events can be duplicated o...

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 ...

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...

CVE-2026-64479 ALSA: seq: Fix uninitialised heap leak in snd_seq_event_dup()

In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: Fix uninitialised heap leak in sndseqeventdup sndseqeventdup copies an incoming event into a pool cell and, in the UMP-enabled build, clears the trailing cell-ump.raw.extra word that the memcpy did not cover. The guard...

CVE-2026-53241

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA sequencer dummy port. This vulnerability arises from a stack overread when processing Universal MIDI Packet UMP events, where the system attempts to copy a UMP-sized packet into a smaller, legacy-sized stack storage. Th...
