Description
A flaw was found in the Linux kernel's MediaTek pin controller (pinctrl) driver, which can lead to a Denial of Service (DoS). When configuring general-purpose input/output (GPIO) pin directions, the driver attempts to acquire a blocking lock while operating in an atomic context. A local attacker could exploit this condition during hardware pin operations to trigger a system lockup or kernel crash.
