Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A use-after-free issue exists in the rt9455 power supply driver. The problem occurs because the interrupt request (IRQ) is requested before the
power supply handle is allocated and registered. Since devm resources are deallocated in reverse order of allocation, the power supply handle is freed before the IRQ handler is unregistered during device removal. This creates a race condition where an interrupt can trigger the power supply changed() function using a freed handle, potentially leading to system crashes or memory corruption. 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 in power supply changed().Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
