What to do

AI-suggested

A fix is available that replaces devm-managed allocations with standard kernel allocations and adds explicit memory free calls. Users should apply the updated Linux kernel patches that address this memory leak in the PHY LED trigger code. No additional mitigation steps are indicated.

Description

A memory leak vulnerability was identified and fixed in the Linux kernel's PHY LED trigger code. The issue was caused by improper use of the devm API, leading to memory not being freed during multiple register/unregister calls for the same PHY device. This could cause out-of-memory conditions during network restart tests on routers.
