Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel where a NULL pointer dereference could occur, leading to a kernel panic. This issue arises from a failure to clear ctx work bits during an error condition on a CLOSE INSTANCE command within the s5p-mfc module. Subsequent execution could then trigger the dereference of a NULL pointer within the context, causing the system to crash.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
