Canonical Releases Important Ubuntu Kernel Security Updates, Patch Now

Canonical already released the other day a new version of the intel-microcode firmware to mitigate the latest Intel vulnerabilities, but now it also published new versions of the Linux kernel for all supported Ubuntu releases, including Ubuntu 20.04 LTS, Ubuntu 19.10, Ubuntu 18.04 LTS, and Ubuntu 16.04 LTS. Apart from mitigating the Intel SRBDS/CrossTalk vulnerability (CVE-2020-0543), the new Linux kernel security updates fix race conditions (CVE-2020-12114) discovered by Piotr Krysiuk in the file system implementation, which lets a local attacker cause a denial of service (system crash).
