Canonical Releases Major Kernel Security Update for Ubuntu 19.10 and 18.04 LTS

The biggest kernel security patch released in December 2019 is for Ubuntu 19.10 (Eoan Ermine) and Ubuntu 18.04 LTS (Bionic Beaver) and fixes 12 vulnerabilities affecting Linux 5.3’s OverlayFS and ShiftFS drivers, the Wi-Fi driver stack, ARM Komeda display driver, VirtualBox guest driver implementation, ADIS16400 IIO IMU driver, and Intel OPA Gen1 Infiniband driver. Issues discovered in the AMD Audio CoProcessor driver, Qualcomm FastRPC driver, Cascoda CA8210 SPI 802.15.4 wireless controller driver, AMD Display Engine driver, and Chelsio T4/T5 RDMA driver were also addressed in this new kernel security update. The majority of these flaws could allow a local attacker to cause a denial of service (memory exhaustion or system crash).
