Security Advisory - Dirty COW Vulnerability in Huawei Products

In the morning of October 21th, 2016, a security researcher Phil Oester disclosed a local privilege escalation vulnerability in Linux kernel. A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write COW breakage of private read-only memory mappings. An...

Dirty Cow Vulnerability Patched in Android Security Bulletin

The Dirty Cow vulnerability lived in Linux for close to a decade, and while it was patched in October in the kernel and in Linux distributions, Android users had to wait for more than a month for their fix. Today, Google included a patch for CVE-2016-5195 in the monthly Android Security Bulletin,...
