Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved, related to the handling of MDIO bus PM operations for phylink-controlled PHYs. The issue affects DSA drivers that do not have MAC managed PM, causing the PHY state machine to run unexpectedly. This can lead to a warning being triggered and potentially cause the kernel to crash. The problem is not limited to DSA drivers but can also affect other MAC drivers with phylink and MDIO-bus-managed PHY PM operations.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
