## Machine-written summary

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

> The Linux kernel qla2xxx SCSI driver is affected from 4.10 until fixed in 5.10.273, 5.15.224, 6.1.191, 6.6.157, or later releases in those series. A late response interrupt during queue-pair deletion can cause a use-after-free, and the source does not say what an attacker needs. Upgrade to a fixed version.
