  • CVE-2018-14634

  • CVE-2017-1000365

    Bypass of the size restriction on the arguments and environment variables of a process.

    The Linux kernel imposes a size limit on the memory needed to store the arguments and environment variables of a process, 1/4 of the maximum stack size (RLIMIT_STACK). However, the pointers to these data were not taken into account, which allowed attackers to bypass the limit and even exhaust the stack of the process.

  • PSBM-88818

    Kernel crash in __run_hrtimer().

    It was found that the implementation of high resolution timers ('hrtimer' subsystem) did not handle the situation when a timer was started simultaneously with its restart in another thread. As a result, a BUG_ON() could trigger in __run_hrtimer() leading to kernel crash.
  • PSBM-88577

    Soft lockup in xfrm_policy_flush().

    If an error occurred during execution of xfrm_net_init() when a new network namespace was created, xfrm_policy_lock could remain uninitialized. As a result, soft lockup could happen in xfrm_policy_flush() if it tried to acquire the lock after that.
  • PSBM-88561

    ploop: kernel crash in dio_open().

    It was found that the implementation of ploop did not handle errors reported by kthread_create() properly. This could lead to a kernel crash in dio_open().
  • PSBM-87836

    Containers with NFS mounts failed to migrate: CRIU complained about nfs/clntX files.

    It was discovered that a container with NFS mounts could keep the files /var/lib/nfs/rpc_pipefs/nfs/clntX open, even if no NFS server was running there. As a result, CRIU reported errors when the users tried to migrate the container.
  • PSBM-88082

    File systems: insufficient error handling in sget() could lead to excessive memory consumption.

  • PSBM-73001

    sunrpc: potential kernel crash (use after free) in svc_process_common().

  • PSBM-87649

    Potential out-of-bounds read in fuse_dev_splice_write().

  • PSBM-87877

    Processes could get stuck in an unkillable state when using large FUSE KIO messages.

    It was found that rpc_get_hdr() function from 'fuse_kio_pcs' module did not return valid values in 'msg_size' in some cases. As a result, the processes using large FUSE KIO messages could get stuck in an unkillable state.
