Overview

CVE-2022-48792 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 SSP/STP sas_task

Currently a use-after-free may occur if a sas_task is aborted by the upper

layer before we handle the I/O completion in mpi_ssp_completion() or

mpi_sata_completion().

In this case, the following are the two steps in handling those I/O

completions:

- Call complete() to inform the upper layer handler of completion of

the I/O.

- Release driver resources associated with the sas_task in

pm8001_ccb_task_free() call.

When complete() is called, the upper layer may free the sas_task. As such,

we should not touch the associated sas_task afterwards, but we do so in the

pm8001_ccb_task_free() call.

Fix by swapping the complete() and pm8001_ccb_task_free() calls ordering.

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.

How can CyberStrike help with CVE-2022-48792?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2022-48792 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
