Ubuntu 0071-1: linux kernel vulnerability
Summary
Update Instructions
The problem can be corrected by updating your kernel livepatch to the following versions: Ubuntu 18.04 LTS aws - 71.1 generic - 71.1 lowlatency - 71.1 oem - 71.1 A mitigation is available if your kernel is affected, did not yet receive a livepatch, and rebooting into the most recently released kernel is not practical. If your system does not require the use of unprivileged user namespaces, you may disable them and mitigate the problem using the following command: sudo sysctl kernel.unprivileged_userns_clone=0 Support Information Kernels older than the levels listed below do not receive livepatch updates. If you are running a kernel version earlier than the one listed below, please upgrade your kernel as soon as possible. Ubuntu 18.04 LTS linux-aws - 4.15.0-1054 linux-oem - 4.15.0-1063 linux - 4.15.0-69 Ubuntu 16.04 LTS linux-azure - 4.15.0-1063 References - CVE-2020-14386 -- ubuntu-security-announce mailing list ubuntu-security-announce@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-security-announce
