## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> Linux kernel versions with the qla2xxx SCSI driver are affected by a use-after-free of queued response-queue work during queue pair teardown, fixed in the listed stable branches. The source gives few details on who can trigger it or what the attacker can achieve. The fix is to update the Linux kernel to a fixed version for your branch, such as 5.10.273, 5.15.224, 6.1.191, or 6.6.160 or later within those branches.
