  script_tag(name:"insight", value:"The openSUSE Leap 15.2 kernel was updated to receive various security and
     bugfixes.

     The following security bugs were fixed:

  - CVE-2018-13405: The inode_init_owner function in fs/inode.c allowed
       local users to create files with an unintended group ownership, in a
       scenario where a directory is SGID to a certain group and is writable by
       a user who is not a member of that group. Here, the non-member can
       trigger creation of a plain file whose group ownership is that group.
       The intended behavior was that the non-member can trigger creation of a
       directory (but not a plain file) whose group ownership is that group.
       The non-member can escalate privileges by making the plain file
       executable and SGID (bnc#1100416 bnc#1129735).

  - CVE-2021-33033: The Linux kernel had a use-after-free in cipso_v4_genopt
       in net/ipv4/cipso_ipv4.c because the CIPSO and CALIPSO refcounting for
       the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads to
       writing an arbitrary value (bnc#1186109 bnc#1188876).

  - CVE-2021-34556: An unprivileged BPF program can obtain sensitive
       information from kernel memory via a Speculative Store Bypass
       side-channel attack because the protection mechanism neglects the
       possibility of uninitialized memory locations on the BPF stack
       (bnc#1188983).

  - CVE-2021-35477: An unprivileged BPF program can obtain sensitive
       information from kernel memory via a Speculative Store Bypass
       side-channel attack because a certain preempting store operation did not
       necessarily occur before a store operation that has an
       attacker-controlled value (bnc#1188985).

  - CVE-2021-3655: Missing size validations on inbound SCTP packets may have
       allowed the kernel to read uninitialized memory (bnc#1188563
       bnc#1192267).

  - CVE-2021-3715: Fixed a use-after-free in route4_change() in
       net/sched/cls_route.c (bsc#1190349).

  - CVE-2021-3760: Fixed a use-after-free vulnerability with the
       ndev- rf_conn_info object (bsc#1190067).

  - CVE-2021-3772: Invalid chunks may be used to remotely remove existing
       associations (bsc#1190351).

  - CVE-2021-3896: Fixed a array-index-out-bounds in detach_capi_ctr in
       drivers/isdn/capi/kcapi.c (bsc#1191958).

  - CVE-2021-41864: prealloc_elems_and_freelist in kernel/bpf/stackmap.c
       allowed unprivileged users to trigger an eBPF multiplication integer
       overflow with a resultant out-of-bounds write (bnc#1191317).

  - CVE-2021-42008: The decode_data function in ...
