And it now looks like the first Kernel Live Patch Security Notice was published by Canonical’s Luis Henriques this past weekend, informing Ubuntu 16.04 LTS users that a couple of security issues are affecting the “generic” and “low-latency” 64-bit kernels of the Xenial Xerus release and its official derivatives. The first Linux kernel vulnerability patched in this kernel patch is the infamous “Dirty COW” bug (CVE-2016-5195), a race condition discovered in Linux kernel’s memory manager when handling copy-on-write breakage of read-only memory mappings, which could have allowed a local attacker to gain administrative privileges (root access).
