Canonical Releases Major Linux Kernel Updates for All Supported Ubuntu OSes


canonical-releases-majorCanonical, the company behind the world’s most popular free operating system, Ubuntu Linux, has published multiple Ubuntu Security Notices to inform users about major kernel updates for all of its supported Ubuntu OSes.

For all systems, the update addresses a use-after-free vulnerability in Linux kernel’s AF_UNIX implementation, which could have allowed a local attacker to expose sensitive information or crash the host system by causing a denial-of-service (DoS) attack by crafting epoll_ctl calls, as well as a security flaw in Linux kernel’s Kernel-based Virtual Machine (KVM) implementation leading to DoS attacks.
