CVE-2026-97537Hinoki check available

Kernel panic via unsafe qla2xxx queue teardown

Published Sep 25, 2026 · Updated Sep 25, 2026

Improper queue teardown in Linux before 6.18.53 or 7.2.7 allows attackers to trigger a kernel panic during qla2xxx queue creation. The qla25xx free routines pass a null ring to dma_free_coherent and modify queue maps under a lock different from the creation lock. Reaching the faulty paths requires the qla2xxx driver and either failed DMA allocation or concurrent queue creation and teardown, with impact limited to system availability.
