Canonical Outs New Linux Kernel Security Patch for All Supported Ubuntu Releases

Available now for the Ubuntu 18.04 LTS (Bionic Beaver), Ubuntu 16.04 LTS (Xenial Xerus), and Ubuntu 14.04 LTS (Trusty Tahr) operating system series, the new Linux kernel security patches address a total of eleven vulnerabilities that affect the Linux 4.15, 4.4, and 3.13 kernels of the aforementioned Ubuntu releases and their derivatives. Among the fixes, we can notice a use-after-free vulnerability (CVE-2018-17182) discovered by Jann Horn in Linux kernel’s vmacache subsystem, which could allow a local attacker crash the system, as well as a stack-based buffer overflow (CVE-2018-14633) in the iSCSI target implementation, which lets a remote attacker crash the system.
