Arch Linux Security Advisory ASA-201610-14 ========================================== Severity: High Date : 2016-10-22 CVE-ID : CVE-2016-5195 Package : linux Type : privilege escalation Remote : No Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package linux before version 4.8.3-1 is vulnerable to privilege escalation. Resolution ========== Upgrade to 4.8.3-1. # pacman -Syu "linux>=4.8.3-1" The problem has been fixed upstream in version 4.8.3. Workaround ========== None. Description =========== 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 unprivileged local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system. Impact ====== An unprivileged local attacker is able to elevate their privileges on the system and gain root access.
