Description
A vulnerability in the Linux kernel's qla2xxx SCSI driver was resolved by adding validation for a pointer before freeing associated memory. This flaw could cause a system crash due to a NULL pointer dereference. The issue was identified by kernel crash logs showing a NULL pointer dereference in the qla2xxx driver. The vulnerability has a medium severity with a CVSS score of 5.5 and affects specific Linux kernel versions. Multiple Linux kernel security issues, including this one, were fixed in an update released by Ubuntu.
