New Ubuntu Linux Kernel Updates Fix 19 Vulnerabilities, Patch Now
Canonical has published new Linux kernel updates for all supported Ubuntu LTS systems to address a total of 19 security vulnerabilities.
The new Ubuntu kernel updates are available only for long-term supported Ubuntu systems, including Ubuntu 22.04 LTS (Jammy Jellyfish), Ubuntu 20.04 LTS (Focal Fossa), and Ubuntu 18.04 LTS (Bionic Beaver).
These Ubuntu kernel updates are here to patch up to 19 vulnerabilities, including CVE-2022-41849 and CVE-2022-41850, two race conditions discovered in the Roccat HID and SMSC UFX USB drivers that could lead to use-after-free vulnerabilities. These affect all Ubuntu LTS systems mentioned above and could allow local and physically proximate attackers to cause a denial of service (system crash) or execute arbitrary code.
Three other vulnerabilities affected Ubuntu 22.04 LTS and Ubuntu 20.04 LTS systems running Linux kernel 5.15 LTS, as well as Ubuntu 20.04 LTS and Ubuntu 18.04 LTS systems running Linux kernel 5.4 LTS.
