Canonical Releases Major Linux Kernel Updates for all 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.
