Vulnerability from fkie_nvd - Published: 2026-03-25 11:16 - Updated: 2026-05-28 14:31

Severity

Summary

In the Linux kernel, the following vulnerability has been resolved: scsi: pm8001: Fix use-after-free in pm8001_queue_command() Commit e29c47fe8946 ("scsi: pm8001: Simplify pm8001_task_exec()") refactors pm8001_queue_command(), however it introduces a potential cause of a double free scenario when it changes the function to return -ENODEV in case of phy down/device gone state. In this path, pm8001_queue_command() updates task status and calls task_done to indicate to upper layer that the task has been handled. However, this also frees the underlying SAS task. A -ENODEV is then returned to the caller. When libsas sas_ata_qc_issue() receives this error value, it assumes the task wasn't handled/queued by LLDD and proceeds to clean up and free the task again, resulting in a double free. Since pm8001_queue_command() handles the SAS task in this case, it should return 0 to the caller indicating that the task has been handled.

A -ENODEV is then\nreturned to the caller. When libsas sas_ata_qc_issue() receives this error\nvalue, it assumes the task wasn\u0027t 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."
