Overview

CVE-2022-49061 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:

net: ethernet: stmmac: fix altr_tse_pcs function when using a fixed-link

When using a fixed-link, the altr_tse_pcs driver crashes

due to null-pointer dereference as no phy_device is provided to

tse_pcs_fix_mac_speed function. Fix this by adding a check for

phy_dev before calling the tse_pcs_fix_mac_speed() function.

Also clean up the tse_pcs_fix_mac_speed function a bit. There is

no need to check for splitter_base and sgmii_adapter_base

because the driver will fail if these 2 variables are not

derived from the device tree.

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.
