CVE-2018-17972

Priority
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.
Ubuntu-Description
Jann Horn discovered that the procfs file system implementation in the
Linux kernel did not properly restrict the ability to inspect the kernel
stack of an arbitrary task. A local attacker could use this to expose
sensitive information.
