CVE-2023-52985

Estado: AnalizadaMedia (5.5)—

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

arm64: dts: imx8mm-verdin: Do not power down eth-phy

Currently if suspending using either freeze or memory state, the fec driver tries to power down the phy which leads to crash of the kernel and non-responsible kernel with the following call trace:

Since there is currently no functionality in the phy subsystem to power down phys let's just disable the feature of powering-down the ethernet phy.
