Background
The Kernel package is a crucial component of the Linux operating system. It provides the core functionality and acts as an interface between the hardware and software layers. The mtd (Memory Technology Devices) subsystem within the Kernel handles flash memory devices, including NAND flash. The rawnand driver is responsible for managing NAND flash devices that use the GPMI (General-Purpose Memory Interface) controller. This vulnerability specifically affects the rawnand GPMI driver.
Vulnerability Detail
The vulnerability in the rawnand GPMI driver allows for the leakage of a PM (Power Management) reference in an error path. This reference leak can lead to incorrect power management handling, potentially resulting in system instability or crashes. An attacker with local access to the system may be able to exploit this vulnerability to escalate privileges or cause denial of service.
