Canonical Releases Linux Kernel Security Patch for Ubuntu 18.04 LTS, Update Now

The kernel security update released by Canonical for Ubuntu 18.04 LTS users patches a security flaw (CVE-2018-1118) discovered in Linux kernel’s VirtIO subsystem, which could allow a local attacker to expose sensitive information (kernel memory) as it improperly initialized memory under certain conditions. The second security vulnerability patched by today’s kernel update addresses an information leak (CVE-2017-13695) discovered by Seunghun Han in Linux kernel’s ACPI (Advanced Configuration and Power Interface) handling code, allowing a local attacker to expose sensitive information (kernel address locations).
