Description

A flaw was found in the Linux kernel, specifically within the power supply subsystem. This vulnerability, a use-after-free, occurs due to a race condition during the removal or initialization of a power supply device. An interrupt can fire after the associated memory for a power supply handle has been released, or before it has been properly set up. This can lead to the system attempting to access invalid memory, which typically results in a system crash, causing a denial of service (DoS). In some scenarios, this memory corruption could potentially be leveraged by a local attacker to achieve further impact.

Mitigation

No mitigation is specified in collected source.
