December 2019 release of the largest kernel security patches apply to Ubuntu 19.10 (Eoan Ermine) and Ubuntu 18.04 LTS (Bionic Beaver), and fixed 12 affect Linux 5.3 of OverlayFS and ShiftFS drivers, Wi-Fi driver stack, vulnerability ARM Komeda display drivers, VirtualBox guest driver implementation, ADIS16400 IIO IMU drivers and Intel OPA Gen1 Infiniband driver.
In this new security kernel update, AMD also addresses audio coprocessor driver, Qualcomm FastRPC driver, Cascoda CA8210 SPI 802.15.4 radio controller driver, AMD Display Engine drivers and Chelsio T4 / T5 RDMA drive problems found in the program. Most of these defects could allow a local attacker to denial of service (memory exhaustion or system crash).
The new kernel security patches may affect Ubuntu 19.04 (Disco Dingo) and Ubuntu 18.04.3 LTS (Bionic Beaver) version of the Linux 5.0 kernel, fixes a buffer found in 802.11 Wi-Fi configuration interface overflow vulnerability could cause local an attacker could cause a denial of service (system crash) or possibly execute arbitrary code, and find memory leaks in the advanced buffer management function Netronome NFP4000 / NFP6000 NIC driver program.
It urged users to update their systems immediately
For Ubuntu 16.04 LTS (Xenial Xerus) operating system family of Linux 4.4 kernel also fixes infinite loop CFS Linux kernel process scheduler found in the circulation may allow a local attacker to cause a denial of service. It urged users to install the update to the new kernel version in the main archive available as soon as possible.
