  • PSBM-94270

    ploop: kernel crash in ploop_congested().

  • PSBM-93988

    ext4: inode tables created during online resize were not zeroed.

    It was discovered that inode tables created during online resize of an ext4 filesystem were not zeroed after that. This could potentially result in lower performance of the filesystem.
  • PSBM-94429

    Windows Server 2016 Essentials failed to install into a QEMU VM with disabled PMU.

    It was found that if no PMU counters were exposed to guest, KVM skipped the whole remaining PMU-related initialization, including filling of LBR-related data. As it turned out, Windows Server 2016 Essentials tried to access these data during the installation and failed to install as a result.
  • PSBM-94727

    ploop: 'pcompact' could hang if run simultaneously with 'ploop-balloon status'

  • PSBM-94535

    Memory leak in the implementation of IPv4 routing.

    It was discovered that a certain sequence of operations related to IPv4 routing could trigger a kernel memory leak. An attacker could potentially exploit that from a container to cause a denial of service.
  • PSBM-94398

    Freeing of a memory cgroup took longer than needed in certain cases.
  • PSBM-94269

    Kernel crash in memcg_css_release_check_kmem().

    It was found that the memcg ID number of a cgroup was released earlier than needed and could then be reused by a different cgroup. As a result, certain reference counters could be corrupted, leading to a kernel crash in memcg_css_release_check_kmem().
  • VSTOR-22272

    I/O errors were reported after a successful replacement of the ploop images.

  • VSTOR-22414

    'ploop replace' did not clear 'abort' flag.

    It was found that if a ploop image was revoked and then replaced using 'ploop replace', 'abort' flag was not cleared. As a result, subsequent I/O operations would fail.
