In the Linux kernel, the following vulnerability has been resolved: net: phy: leds: fix memory leak A network restart test on a router led to an out-of-memory condition, which was traced to a memory leak in the PHY LED trigger code. The root cause is misuse of the devm API. The registration function (phy_led_triggers_register) is called from phy_attach_direct, not phy_probe, and the unregister function (phy_led_triggers_unregister) is called from phy_detach, not phy_remove. This means the register and unregister functions can be called multiple times for the same PHY device, but devm-allocated
