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

Description A flaw exists in the Linux kernel's ethernet functionality, specifically within the mtk eth soc module and the mtk hwlro get fdir all() function. The issue involves a potential NULL pointer dereference that can occur because the size of rule locs is determined by rule cnt received from user space, and this value is not adequately validated before being used. This could lead to a system crash or other unexpected behavior.

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