Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A use-after-free issue exists in the power supply changed() function. The problem occurs because the devm variant for requesting an IRQ is used before the devm variant for allocating or registering the power supply handle. Since devm deallocates resources in reverse allocation order, the power supply handle is freed before the interrupt handler is unregistered during removal. This creates a race condition where an interrupt can trigger the IRQ handler to call power supply changed() using a freed power supply handle, potentially leading to system crashes or memory corruption. Additionally, a similar race condition can occur during the probe() process, where an interrupt might fire before the power supply handle is registered, resulting in the use of an uninitialized handle.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
