CVE-2014-7825

Published: 10 November 2014

kernel/trace/trace_syscalls.c in the Linux kernel through 3.17.2 does not properly handle private syscall numbers during use of the perf subsystem, which allows local users to cause a denial of service (out-of-bounds read and OOPS) or bypass the ASLR protection mechanism via a crafted application.

From the Ubuntu security team

Rabin Vincent, Robert Swiecki, Russell Kinglaw discovered a flaw in how the perf subsystem of the Linux kernel handles private systecall numbers. A local user could exploit this to cause a denial of service (OOPS) or bypass ASLR protections via a crafted application.
