Description
In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix deletion race condition System crash when using debug kernel due to link list corruption. The cause of the link list corruption is due to session deletion was allowed to queue up twice. Here's the internal trace that show the same port was allowed to double queue for deletion on different cpu. 20808683956 015 qla2xxx [0000:13:00.1]-e801:4: Scheduling sess ffff93ebf9306800 for deletion 50:06:0e:80:12:48:ff:50 fc4_type 1 20808683957 027 qla2xxx [0000:13:00.1]-e801:4: Scheduling sess ffff93ebf9306800 for deletion 50:06:0e:80:12:48:ff:50 fc4_type 1 Move the clearing/setting of deleted flag lock.

Executive Summary

This vulnerability is a race condition in the Linux kernel's qla2xxx SCSI driver where a session deletion operation could be queued twice on different CPUs. This leads to corruption of a linked list and can cause a system crash, especially when using a debug kernel. The issue arises because the deletion flag was not properly locked during clearing and setting, allowing double queuing of the same session for deletion.

Impact Analysis

The vulnerability can cause system crashes due to linked list corruption when the affected qla2xxx driver attempts to delete a session twice concurrently. This can lead to instability or downtime on systems using this driver, particularly in environments running debug kernels.
