Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel up to 6.15.2. This affects some unknown functionality of the component net. The impact remains unknown. The summary by CVE is:

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.
