Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.14.0-503.11.1.el9 5

Description The Linux kernel contains a flaw within the qla2xxx SCSI driver related to memory management. Specifically, the code does not validate a pointer (sp) before attempting to free associated memory. This can lead to a kernel NULL pointer dereference, resulting in a system crash. The crash signature involves the qla2xxx driver and indicates a read access violation in kernel mode.

Recommendations Update the Linux kernel to version 5.14.0-503.11.1.el9 5 or a later version to resolve this issue.
