CVE-2019-13272

A flaw was found in the way PTRACE_TRACEME functionality was handled in the Linux kernel. The kernel’s implementation of ptrace can inadvertently grant elevated permissions to an attacker who can then abuse the relationship between the tracer and the process being traced. This flaw could allow a local, unprivileged user to increase their privileges on the system or cause a denial of service.
