Linux Kernel SCSI PM8001 Task Leak Vulnerability

A vulnerability in the Linux kernel's SCSI PM8001 driver has been addressed, which involved a task leak in the 'pm8001_send_abort_all()' function. The issue arose because the function failed to properly free allocated SAS tasks when 'pm8001_tag_alloc()' or 'pm8001_mpi_build_cmd()' encountered errors.

Impact

Exploitation of this vulnerability could lead to a memory leak, where allocated SAS tasks are not properly released, potentially causing increased memory usage and degradation of system performance over time.
