Also fetch the initial proc read iterator only after taking setup_mutex, so all setup_list traversal follows the same list lifetime rules.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>ALSA: pcm: oss: Fix setup list UAF on proc write error</p> <p>snd_pcm_oss_proc_write() links a newly allocated setup entry into the OSS setup list before duplicating the task name.
