Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw within the
qla2xxx module related to an unused nvme ls waitq wait queue. A system crash can occur when qla2x00 start sp(sp) returns an EGAIN error code, leading to a call to wake up for an uninitialized wait queue (sp->nvme ls waitq). This results in a kernel NULL pointer dereference. The nvme ls waitq logic has been removed in previous commits.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
