## Machine-written summary

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

> The Linux kernel qla2xxx SCSI driver's queue teardown code, affected from 2.6.29 until fixed, frees a NULL DMA buffer when queue creation fails and can race on queue ID bookkeeping, which can cause a panic. The source gives few details on what an attacker needs. Upgrade to 5.10.273, 5.15.224, 6.1.191, 6.6.160 or later in those series.
