Technical description

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:

[ 24.839889 ] Call trace:

[ 24.839892 ] phy_error+0x18/0x60

[ 24.839898 ] kszphy_handle_interrupt+0x6c/0x80

[ 24.839903 ] phy_interrupt+0x20/0x2c

[ 24.839909 ] irq_thread_fn+0x30/0xa0

[ 24.839925 ] kthread+0x154/0x160

[ 24.839932 ] ret_from_fork+0x10/0x20

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.

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.
