Overview

CVE-2022-49566 is a medium-severity vulnerability. It was published on February 26, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. 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:

crypto: qat - fix memory leak in RSA

When an RSA key represented in form 2 (as defined in PKCS #1 V2.1) is

used, some components of the private key persist even after the TFM is

released.

Replace the explicit calls to free the buffers in qat_rsa_exit_tfm()

with a call to qat_rsa_clear_ctx() which frees all buffers referenced in

the TFM context.

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.
