A local attacker could use to cause a denial\nof service (system crash) or possibly execute arbitrary code with\nadministrative privileges. (CVE-2016-8632)\n\nDmitry Vyukov discovered that a race condition existed in the timerfd\nsubsystem of the Linux kernel when handling might_cancel queuing. A local\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2017-10661)\n\nIt was discovered that the Flash-Friendly File System (f2fs) implementation\nin the Linux kernel did not properly validate superblock metadata. A local\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2017-10662, CVE-2017-10663)\n\nAnthony Perard discovered that the Xen virtual block driver did not\nproperly initialize some data structures before passing them to user space.\nA local attacker in a guest VM could use this to expose sensitive\ninformation from the host OS or other guest VMs. (CVE-2017-10911)\n\nIt was discovered that a use-after-free vulnerability existed in the POSIX\nmessage queue implementation in the Linux kernel.
