Vulnerability CVE-2024-42313
Published: 2024-08-17

Description:
In the Linux kernel, the following vulnerability has been resolved:

media: venus: fix use after free in vdec_close

There appears to be a possible use after free with vdec_close().
The firmware will add buffer release work to the work queue through
HFI callbacks as a normal part of decoding. Randomly closing the
decoder device from userspace during normal decoding can incur
a read after free for inst.

Fix it by cancelling the work in vdec_close.
