First published: Fri Nov 07 2014(Updated: )
An out-of-bounds memory access flaw was found in the Linux kernel's perf and ftrace subsystems. On a system with syscall perf profiling on (<a href="https://access.redhat.com/security/cve/CVE-2014-7825">CVE-2014-7825</a>) an unprivileged local user could use this flaw to crash the system. On a system with ftrace syscall tracing on (<a href="https://access.redhat.com/security/cve/CVE-2014-7826">CVE-2014-7826</a>) an unprivileged local user could use this flaw to crash the system or escalate their privileges on the system.
