Doc Text:
A flaw was found in the Linux kernel. A race condition existed in the ARM Advanced Microcontroller Bus Architecture (AMBA) driver that could result in a double free. A local attacker could use this to cause a denial of service. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.
