CVE-2018-17972: Race Condition
First published: Wed Oct 03 2018(Updated: )
An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel . An attacker with a local account can trick the stack unwinder code to leak stack contents to userspace. The fix allows only root may inspect the kernel stack of an arbitrary task.
