CVE-2014-4699: Race Condition

First published: Thu Jul 03 2014(Updated: )

It was found that the Linux kernel's ptrace subsystem allowed a traced process' instruction pointer to be set to a non-canonical memory address without forcing the non-sysret code path when returning to user space. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. Note: The CVE-2014-4699 issue only affected systems using an Intel CPU.
