USN-3871-2: Linux kernel regression

USN-3871-1 fixed vulnerabilities in the Linux kernel for Ubuntu 18.04 LTS. Unfortunately, that update introduced regressions with docking station displays and mounting ext4 file systems with the metabg option enabled. This update fixes the problems. We apologize for the inconvenience. Original...

USN-3871-1: Linux kernel vulnerabilities

Wen Xu discovered that a use-after-free vulnerability existed in the ext4 filesystem implementation in the Linux kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service system crash or possibly execute arbitrary code...

CVE-2018-3652

CVE-2018-3652 relates to UEFI DCI (Direct Connect Interface) restrictions on 5th/6th gen Intel Xeon E3, Xeon Scalable, and Xeon D processors. The issue could allow a limited physical presence attacker to access platform secrets via debug interfaces when DCI policy/UEFI controls are in effect. The...
