  • PSBM-101823

    ploop: potential corruption of the index during discard operation.

    A race condition was discovered in ploop, which could lead to corruption of the index during discard operations in certain cases. Note. It is not recommended to manually unload the ReadyKernel patch with the fix for this issue while any discard operations for ploop images are in progress: the ploop images could be corrupted as a result. Upgrading the patch is OK, only manual unloads and downgrades can be problematic.
  • PSBM-102070

    ploop: warn if a discard request is issued for the ploop header.

  • PSBM-102033

    ve: detect removal of additional system libraries in the containers to simplify debugging.

  • PSBM-101783

    Potential leak of a reference counter for a memory cgroup in memcg_expand_shrinker_maps().

  • PSBM-101533

    Potential corruption of ploop images due to a race between the truncation thread and resize operations.

  • PSBM-101595

    ve: make it easier to analyze removal of system libraries in the containers.

  • CVE-2019-15538

    xfs: potential denial of service caused by missing unlock operation in xfs_setattr_nonsize().

    It was discovered that xfs_setattr_nonsize() would not unlock 'ILOCK' lock if the user or group were out of their disk quota. As a result, any subsequent operation, which needed to take 'ILOCK', would get stuck, leading to a denial of service.

  • PSBM-101492

    nf_tables: kernel crash in nft_rbtree_lookup().

  • PSBM-101189

    ploop: holes in raw ploop images were handled incorrectly.

  • PSBM-94695

    Kernel crash due to out-of-bounds memory accesses in process_vm_readv().

    It was discovered that the implementation of process_vm_readv() system call could try to access memory outside of the structures it was processing in certain cases. A local unprivileged user could use this vulnerability to crash the system.
  • PSBM-101159

    quotaoff operation executed in a container could get stuck in D state.

  • PSBM-101143

    Certain operations with an empty ploop image could lead to its unexpected growth.

  • PSBM-101249

    Incomplete fix for PSBM-100575: reading of /proc/bc/resources line by line would never end.

  • PSBM-100509

    memcg: memory corruption caused by writing beyond the end of shrinker_map structure.

  • PSBM-100722

    ixgbe: lots of warnings in the system log due to incorrect check for firmware errors.

  • PSBM-100739

    ploop: kernel crashes when processing discard requests for ploop images in raw format.

  • PSBM-100118

    scsi: printing lots of messages about rejected I/O causes a hard lockup and a kernel crash.

  • PSBM-100593

    Kernel crash in shrink_slab() when trying to mount an image with a broken ext4 file system.

  • PSBM-100575

    Reading of /proc/bc/resources line by line would never end: no end of file was reported.

  • PSBM-100579

    Potential kernel crash in __radix_tree_insert() when fscache is used for NFS mounts.

  • PSBM-99764

    sunrpc: potential kernel crash in bc_svc_process().

  • PSBM-100441

    A bug in ploop prevented recovery of corrupted ploop images.

  • VSTOR-29472

    The minimum amount of reserved free memory (vm.min_free_kbytes) was set too high by default.

  • PSBM-96262

    kvm: potential system hang due to an error in mmu_shrink_scan().

  • PSBM-96057

    Processes could get stuck in copy_net_ns() forever.
