Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A potential crash in the Linux kernel has been identified. The issue occurs when setting up a bsg queue fails, causing the bsg queue to be assigned a non-NULL value. As a result, the condition to remove the queue is not met, leading to a possible kernel NULL pointer dereference. This can happen when the
mpi3mr bsg exit() function is called, and the bsg remove queue() function is not executed, resulting in a crash.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
