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.
