Technical description

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

net: dsa: b53: do not enable EEE on bcm63xx

BCM63xx internal switches do not support EEE, but provide multiple RGMII

ports where external PHYs may be connected. If one of these PHYs are EEE

capable, we may try to enable EEE for the MACs, which then hangs the

system on access of the (non-existent) EEE registers.

Fix this by checking if the switch actually supports EEE before

attempting to configure it.

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.
