An update that solves 11 vulnerabilities and has 62 fixes is now available.


The SUSE Linux Enterprise 15 SP2 Azure kernel was updated to receive various
security and bugfixes.

The following security bugs were fixed:

  o CVE-2021-3347: A use-after-free was discovered in the PI futexes during
    fault handling, allowing local users to execute code in the kernel (bnc#
  o CVE-2021-3348: Fixed a use-after-free in nbd_add_socket that could be
    triggered by local attackers (with access to the nbd device) via an I/O
    request at a certain point during device setup (bnc#1181504).

    rules. A privileged user could insert a rule which could lead to denial of
    service (bnc#1180765).

    corruption due to a use after free. This could lead to local escalation of
    privilege with System execution privileges required. (bnc#1180812)
  o CVE-2020-27835: A use-after-free in the infiniband hfi1 driver was found,
    specifically in the way user calls Ioctl after open dev file and fork. A
    local user could use this flaw to crash the system (bnc#1179878).

    watch events (bnc#1179508).
  o CVE-2020-25211: Fixed a flaw where a local attacker was able to inject
    conntrack netlink configuration that could cause a denial of service or
    trigger the use of incorrect protocol numbers in
    ctnetlink_parse_tuple_filter (bnc#1176395).
  o CVE-2020-36158: Fixed an issue wich might have allowed a remote attackers
    to execute arbitrary code via a long SSID value in
    mwifiex_cmd_802_11_ad_hoc_start() (bnc#1180559).
  o CVE-2020-28374: Fixed a vulnerability caused by insufficient identifier
    checking in the LIO SCSI target code. This could have been used by a remote
    attackers to read or write files via directory traversal in an XCOPY
    request (bnc#1178372).
