Coming hot on the heels of the latest Linux kernel security update released by Canonical on Tuesday, the new Linux kernel live patch security update fixes a total of five security vulnerabilities, which are documented as CVE-2018-11506, CVE-2018-11412, CVE-2018-13406, CVE-2018-13405, and CVE-2018-12233. These include a stack-based buffer overflow (CVE-2018-11506) discovered by Piotr Gabriel Kosinski and Daniel Shapira in Linux kernel’s CDROM driver implementation, which could allow a local attacker to either execute arbitrary code or cause crash the system via a denial of service.
