Description
An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents.
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 to inspect the kernel stack of an arbitrary task.
