Available for the Ubuntu 19.10 (Eoan Ermine), Ubuntu 18.04 LTS (Bionic Beaver), and Ubuntu 16.04 LTS (Xenial Xerus) operating system series, the new Linux kernel security update is here to fix a vulnerability (CVE-2019-14615) affecting systems with Intel Graphics Processing Units (GPUs), which could allow a local attacker to expose sensitive information. It also addresses a race condition (CVE-2019-18683) discovered in the Virtual Video Test Driver (VIVID), which could allow an attacker with write access to /dev/video0 to gain administrative privileges, as well as a flaw (CVE-2019-19241) in Linux kernel’s IO uring implementation that could also allow a local attacker to gain administrative privileges.
