  script_tag(name:"insight", value:"The SUSE Linux Enterprise 15 SP1 LTSS kernel was updated to receive
     various security and bugfixes.

     The following security bugs were fixed:

  - Unprivileged BPF has been disabled by default to reduce attack surface
       as too many security issues have happened in the past (jsc#SLE-22573)

       You can re-enable via systemctl setting
     /proc/sys/kernel/unprivileged_bpf_disabled to 0.
     (kernel.unprivileged_bpf_disabled = 0)

  - CVE-2021-0941: In bpf_skb_change_head of filter.c, there is a possible
       out of bounds read due to a use after free. This could lead to local
       escalation of privilege with System execution privileges needed. User
       interaction is not needed for exploitation (bnc#1192045).

  - CVE-2021-31916: An out-of-bounds (OOB) memory write flaw was found in
       list_devices in drivers/md/dm-ioctl.c in the Multi-device driver module
       in the Linux kernel A bound check failure allowed an attacker with
       special user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds
       memory leading to a system crash or a leak of internal kernel
       information. The highest threat from this vulnerability is to system
       availability (bnc#1192781).

  - CVE-2021-20322: Make the ipv4 and ipv6 ICMP exception caches less
       predictive to avoid information leaks about UDP ports in use.
       (bsc#1191790)

  - CVE-2021-34981: Fixed file refcounting in cmtp when cmtp_attach_device
       fails  (bsc#1191961).

  - CVE-2021-37159: hso_free_net_device in drivers/net/usb/hso.c in the
       Linux kernel calls unregister_netdev without checking for the
       NETREG_REGISTERED state, leading to a use-after-free and a double free
       (bnc#1188601).

  - CVE-2021-3772: Fixed sctp vtag check in sctp_sf_ootb (bsc#1190351).

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

  - CVE-2021-33033: The Linux kernel has 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#1186390 bnc#1188876).

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

  - CVE-2021-42739: The firewire subsystem in the Linux kernel has a buffer
       overflow related to drivers/media/firewire/firedtv-avc.c and
       drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandled
       bounds ...
