CVE-2025-38272

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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: dsa: b53: no habilitar EEE en bcm63xx. Los conmutadores internos BCM63xx no admiten EEE, pero proporcionan múltiples puertos RGMII donde se pueden conectar PHY externos. Si uno de estos PHY admite EEE, podemos intentar habilitar EEE para las MAC, lo que bloquea el sistema al acceder a los registros EEE (inexistentes). Para solucionar esto, verifique si el conmutador admite EEE antes de configurarlo.
