Canonical Releases New Linux Kernel Live Patch for Ubuntu 18.04 and 16.04 LTS

Coming hot on the heels of the last Linux kernel security updates released by Canonical last week for all supported Ubuntu Linux releases, this new kernel live patch is now available for users of the Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 16.04 LTS (Xenial Xerus) operating systems who use the Canonical Livepatch Service to apply rebootless kernel updates. It fixes five security issues, including a race condition (CVE-2019-11815), which could lead to a use-after-free, in Linux kernel’s RDS (Reliable Datagram Sockets) protocol implementation that may allow a local attacker to crash the system or execute arbitrary code, as well as a flaw (CVE-2019-2054) affecting ARM CPUs, which lets local attackers to bypass seccomp restrictions.
