Arch Linux Security Advisory ASA-201710-24 ========================================== Severity: High Date : 2017-10-16 CVE-ID : CVE-2017-5123 Package : linux-zen Type : privilege escalation Remote : No Link : https://security.archlinux.org/AVG-445 Summary ======= The package linux-zen before version 4.13.7-1 is vulnerable to privilege escalation. Resolution ========== Upgrade to 4.13.7-1. # pacman -Syu "linux-zen>=4.13.7-1" The problem has been fixed upstream in version 4.13.7. Workaround ========== None. Description =========== It was discovered that when the waitid() syscall in Linux kernel v4.13 was refactored, it accidentally stopped checking that the incoming argument was pointing to userspace. This allowed local attackers to write directly to kernel memory, which could lead to privilege escalation. Impact ====== A local attacker is able to escalate privileges on the affected host.
