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...

kernel: race condition in snd_seq_write() may lead to UAF or OOB-access

ALSA sequencer core initializes the event pool on demand by invoking sndseqpoolinit when the first write happens and the pool is empty. A user can reset the pool size manually via ioctl concurrently, and this may lead to UAF or out-of-bound access...
