Overview

CVE-2022-48791 is a high-severity vulnerability. It was published on July 16, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

scsi: pm8001: Fix use-after-free for aborted TMF sas_task

Currently a use-after-free may occur if a TMF sas_task is aborted before we

handle the IO completion in mpi_ssp_completion(). The abort occurs due to

timeout.

When the timeout occurs, the SAS_TASK_STATE_ABORTED flag is set and the

sas_task is freed in pm8001_exec_internal_tmf_task().

However, if the I/O completion occurs later, the I/O completion still

thinks that the sas_task is available. Fix this by clearing the ccb->task

if the TMF times out - the I/O completion handler does nothing if this

pointer is cleared.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
