Technical description

In the Linux kernel, the following vulnerability has been resolved:

scsi: qla2xxx: Clear cmds after chip reset

Commit aefed3e5548f ("scsi: qla2xxx: target: Fix offline port handling

and host reset handling") caused two problems:

1. Commands sent to FW, after chip reset got stuck and never freed as FW

is not going to respond to them anymore.

2. BUG_ON(cmd->sg_mapped) in qlt_free_cmd(). Commit 26f9ce53817a

("scsi: qla2xxx: Fix missed DMA unmap for aborted commands")

attempted to fix this, but introduced another bug under different

circumstances when two different CPUs were racing to call

qlt_unmap_sg() at the same time: BUG_ON(!valid_dma_direction(dir)) in

dma_unmap_sg_attrs().

So revert "scsi: qla2xxx: Fix missed DMA unmap for aborted commands" and

partially revert "scsi: qla2xxx: target: Fix offline port handling and

host reset handling" at __qla2x00_abort_all_cmds.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
