Description
A flaw was found in the Linux kernel's accel/rocket driver. This flaw can lead to a Denial of Service (DoS) through a system crash under specific hardware initialization failure conditions. If initial device setup fails, the driver does not properly clear an internal reference pointer, leaving an invalid error pointer. A subsequent core probe can then dereference this invalid pointer, crashing the operating system.
