Canonical released a new kernel live patch for all of its LTS (Long Term Support) Ubuntu Linux releases to address various security vulnerabilities discovered by various security researchers lately.
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.
