CVSSv3

A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc.

CVSSv3

A use-after-free flaw was found in the Linux kernel's NFC core functionality due to a race condition between kobject creation and delete. This vulnerability allows a local attacker with CAP_NET_ADMIN privilege to leak kernel information.
