Description
A flaw was found in the Linux kernel's TC9563 power control driver. When parsing device tree nodes for the integrated Ethernet endpoint during device initialization, the driver improperly processes multiple functions, causing an out-of-bounds array access. A local attacker capable of supplying or modifying device tree configurations could exploit this flaw to cause memory corruption, potentially resulting in a system crash and a Denial of Service (DoS).
