However, the\niSCSI target doesn't trigger the completion process for these aborted\ncommands. Because of this, the abort path hangs indefinitely in\ntarget_put_cmd_and_wait(), leading to a deadlocked target worker thread.\n\nFix this by explicitly calling target_complete_cmd() when the final\ndataout PDU is received for an aborted WRITE command.\ntarget_complete_cmd() detects the CMD_T_ABORTED flag and cleanly routes\nthe command into target_abort_work, allowing the abort completion to\nsuccessfully unblock.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
