    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: pm8001: Fix use-after-free in pm8001_queue_command()\n\nCommit e29c47fe8946 (\"scsi: pm8001: Simplify pm8001_task_exec()\") refactors\npm8001_queue_command(), however it introduces a potential cause of a double\nfree scenario when it changes the function to return -ENODEV in case of phy\ndown/device gone state.\n\nIn this path, pm8001_queue_command() updates task status and calls\ntask_done to indicate to upper layer that the task has been handled.\nHowever, this also frees the underlying SAS task. A -ENODEV is then\nreturned to the caller. When libsas sas_ata_qc_issue() receives this error\nvalue, it assumes the task wasn't handled/queued by LLDD and proceeds to\nclean up and free the task again, resulting in a double free.\n\nSince pm8001_queue_command() handles the SAS task in this case, it should\nreturn 0 to the caller indicating that the task has been handled.",
