CVE-2015-7613
Published: 02 October 2015
Race condition in the IPC object implementation in the Linux kernel through 4.2.3 allows local users to gain privileges by triggering an ipc_addid call that leads to uid and gid comparisons against uninitialized data, related to msg.c, shm.c, and util.c.
From the Ubuntu security team
Dmitry Vyukov discovered that the Linux kernel did not properly initialize IPC object state in certain situations. A local attacker could use this to escalate their privileges, expose confidential information, or cause a denial of service (system crash).
