A flaw was found in the Linux kernel. A local user could exploit a vulnerability in the GPIO (General Purpose Input/Output) reset controller by unbinding a dynamically created device through the sysfs (a virtual filesystem providing an interface to kernel data structures) interface. This improper handling of device unbinding can lead to a use-after-free condition, which may result in system instability or a denial of service.
