Linux Kernel GPIO Charger Charge Current Limit Vulnerability

A vulnerability in the Linux kernel's power supply GPIO charger component allows for improper handling of charge current limits. This issue affects devices that can set the lowest charge current limit above zero. When a requested charge current limit falls below this minimum, the system erroneously accesses memory beyond what has been allocated, potentially leading to memory corruption.

Impact

Exploitation of this vulnerability could result in memory corruption by accessing out-of-bounds memory, which may lead to undefined behavior such as arbitrary code execution or causing a system crash.
