CVE-2016-7911

Published: 16 November 2016

Race condition in the get_task_ioprio function in block/ioprio.c in the Linux kernel before 4.6.6 allows local users to gain privileges or cause a denial of service (use-after-free) via a crafted ioprio_get system call.

From the Ubuntu security team

Dmitry Vyukov discovered a use-after-free vulnerability in the sys_ioprio_get() function in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges.
