CVE-2025-68745

Description

In the Linux kernel, the following vulnerability has been resolved:scsi: qla2xxx: Clear cmds after chip resetCommit aefed3e5548f (scsi: qla2xxx: target: Fix offline port handlingand 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 andpartially revert scsi: qla2xxx: target: Fix offline port handling andhost reset handling at __qla2x00_abort_all_cmds.
