Description
A flaw was found in the Linux kernel's pm8001 SCSI driver. When pm8001_request_msix() attempts to free Message Signaled Interrupts (MSI-X) vectors, it uses an incorrect index during the rollback process. This error prevents previously registered interrupt handlers from being properly deallocated, leading to resource leaks. A local attacker could potentially exploit this to cause system instability or a denial of service.
