CVE-2026-64001

In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: oss: Fix setup list UAF on proc write error snd_pcm_oss_proc_write() links a newly allocated setup entry into the OSS setup list before duplicating the task name. If the task-name allocation fails, the error path frees the already linked entry and leaves setup_list pointing at freed memory. A later OSS device open can then walk the stale list entry in snd_pcm_oss_look_for_setup() and dereference freed memory. Allocate the task name and initialize the setup entry before publishing the entry on setup_list. Also fetch the initial proc read iterator only after taking setup_mutex, so all setup_list traversal follows the same list lifetime rules.
