Name of the Vulnerable Software and Affected Versions Linux Kernel versions prior to v4.19.272

Description The issue concerns the validation of the addr parameter in the mdiobus get phy() function. This is an automated identification of a potential security issue, but the actual impact and attack plausibility have not been proven yet.

Recommendations For Linux Kernel versions prior to v4.19.272, update to version v4.19.272 or later to resolve the issue. As a temporary workaround, consider validating the addr parameter in the mdiobus get phy() function to minimize the risk of exploitation.
