0.006 Low




An update that solves 21 vulnerabilities and has 74 fixes
is now available.


The openSUSE Leap 15.2 kernel was updated to receive various security and

The following security bugs were fixed:

  • CVE-2021-3444: Fixed an issue with the bpf verifier which did not
    properly handle mod32 destination register truncation when the source
    register was known to be 0 leading to out of bounds read (bsc#1184170).
  • CVE-2021-3428: Fixed an integer overflow in ext4_es_cache_extent
  • CVE-2021-29647: Fixed an issue in qrtr_recvmsg which could have allowed
    attackers to obtain sensitive information from kernel memory because of

  • CVE-2021-28972: Fixed a user-tolerable buffer overflow when writing a
    new device name to the driver from userspace, allowing userspace to
    write data to the kernel stack frame directly (bsc#1184198).
  • CVE-2021-28971: Fixed an issue in intel_pmu_drain_pebs_nhm which could
    have caused a system crash because the PEBS status in a PEBS record was

    necessary treatment of errors such as failed memory allocations

    Netlink message that is associated with iSCSI, and has a length up to
    the maximum length of a Netlink message (bsc#1182715).
  • CVE-2021-27364: Fixed an issue where an attacker could craft Netlink
    messages (bsc#1182717).

    x25_bind (bsc#1183696).

    speculation on pointer arithmetic, leading to side-channel attacks that
    defeat Spectre mitigations and obtain sensitive information from kernel
    memory (bsc#1183775).
  • CVE-2020-27170: Fixed potential side-channel attacks that defeat Spectre
    mitigations and obtain sensitive information from kernel memory
