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.
