kernel: x86_64: ptrace: sysret to non-canonical address
Published Jul 9, 2014

MEDIUMCVSS 2.0
EPSS 2.32%
Description
The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allows local users to leverage a race condition and gain privileges, or cause a denial of service (double fault), via a crafted application that makes ptrace and fork system calls.
