  • PSBM-70151

    A container could not be stopped in certain situations because of an infinite loop in __get_user_pages().

    If transparent huge pages were enabled, certain processes could enter an infinite loop in __get_user_pages() and become unkillable preventing the container from stopping.
  • PSBM-69999

    Kernel crashes in memcg_numa_migrate_write() during NUMA balancing.

    It was found that memcg_numa_isolate_pages() used unsafe operations with lists, which lead to kernel crashes in memcg_numa_migrate_write() during NUMA balancing.
  • PSBM-69852

    tcache: wrong memory pages were invalidated in some cases.

    It was found that wrong memory pages were invalidated in tcache in certain situations. That caused kernel crashes ("bad page state") in free_pages_prepare().
  • PSBM-70063

    Race on map->levels[] update in ploop.

    ploop could use inconsistent values for iblock and the corresponding delta for IO because of a race over map->levels[]. This could result in incorrect read and write operations for ploop devices.
  • CVE-2017-1000112

    A race condition in the UDP Fragmentation Offload (UFO).

    Andrey Konovalov discovered a race condition in the UDP Fragmentation Offload (UFO) code in the Linux kernel. A local attacker could use this to cause a denial of service or execute arbitrary code.

  • CVE-2017-1000111

    Heap out-of-bounds in AF_PACKET sockets.

    Andrey Konovalov discovered a race condition in AF_PACKET socket option handling code which may result in out-of-bounds accesses to the heap memory. A local unprivileged attacker could use this to cause a denial of service or possibly execute arbitrary code.

  • CVE-2017-7533

    A race between inotify_handle_event() and sys_rename().

    Fan Wu and Shixiong Zhao discovered a race condition between inotify events and vfs rename operations in the Linux kernel. An unprivileged local attacker could use this to cause a denial of service (system crash) or execute arbitrary code.

  • PSBM-69434

    Kernel crash (BUG()) in rpc_abort_task().

    Kernel crash (BUG()) in rpc_abort_task().
  • CVE-2017-7541

    Possible heap buffer overflow in brcmf_cfg80211_mgmt_tx().

    Kernel memory corruption due to a buffer overflow was found in brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to v4.13-rc1. The vulnerability can be triggered by sending a crafted NL80211_CMD_FRAME packet via netlink. An unprivileged local user could use this flaw to induce kernel memory corruption on the system, leading to a crash.
