| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A use-after-free issue may occur in the Linux kernel when a sas task is aborted by the upper layer before handling the I/O completion in
mpi ssp completion() or mpi sata completion(). This happens because the upper layer may free the sas task after calling complete(), but the kernel still tries to access it in pm8001 ccb task free(). The issue is resolved by swapping the order of the complete() and pm8001 ccb task free() calls.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
