In the Linux kernel, the following vulnerability has been resolved:media: venus: fix use after free in vdec_closeThere appears to be a possible use after free with vdec_close().The firmware will add buffer release work to the work queue throughHFI callbacks as a normal part of decoding. Randomly closing thedecoder device from userspace during normal decoding can incura read after free for inst.Fix it by cancelling the work in vdec_close.
