Overview

CVE-2022-49089 is a high-severity vulnerability. It was published on February 26, 2025 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:

IB/rdmavt: add lock to call to rvt_error_qp to prevent a race condition

The documentation of the function rvt_error_qp says both r_lock and s_lock

need to be held when calling that function. It also asserts using lockdep

that both of those locks are held. However, the commit I referenced in

Fixes accidentally makes the call to rvt_error_qp in rvt_ruc_loopback no

longer covered by r_lock. This results in the lockdep assertion failing

and also possibly in a race condition.

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.
