Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
media: iris: Fix use-after-free in iris_release_internal_buffers()<br />
<br />
The recent change in commit 1dabf00ee206 ("media: iris: gen1: Destroy<br />
internal buffers after FW releases") introduced a regression where<br />
session_release_buf() may free the buffer. The caller,<br />
iris_release_internal_buffers(), continued to access `buffer` after the<br />
call, leading to a potential use-after-free.<br />
<br />
Fix this by setting BUF_ATTR_PENDING_RELEASE before calling<br />
session_release_buf(), and reverting the flag if the call fails. This<br />
ensures no dereference occurs after potential freeing.
