______________________________________________________________________________

An update that solves 14 vulnerabilities and has 24 fixes is now available.

Description:

The SUSE Linux Enterprise 12 SP5 Real Time kernel was updated to receive
various security and bugfixes.

The following security bugs were fixed:

  o CVE-2021-3655: Fixed a missing size validations on inbound SCTP packets,
    which may have allowed the kernel to read uninitialized memory (bsc#
    1188563).
  o CVE-2021-3715: Fixed a use-after-free in route4_change() in net/sched/
    cls_route.c (bsc#1190349).
  o CVE-2021-33033: Fixed 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 (bsc#1186109).
  o CVE-2021-3760: Fixed a use-after-free vulnerability with the ndev->
    rf_conn_info object (bsc#1190067).
  o CVE-2021-42739: The firewire subsystem had a buffer overflow related to
    drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/
    firedtv-ci.c, because avc_ca_pmt mishandled bounds checking (bsc#1184673).
  o CVE-2021-3542: Fixed heap buffer overflow in firedtv driver (bsc#1186063).

    from kernel memory (bsc#1188983).
  o CVE-2021-35477: Fixed BPF stack frame pointer which could have been abused
    to disclose content of arbitrary kernel memory (bsc#1188985).

    allowed local attackers to access the Aspeed LPC control interface to
    overwrite memory in the kernel and potentially execute privileges (bnc#
    1190479).
  o CVE-2021-41864: Fixed prealloc_elems_and_freelist that allowed unprivileged
    users to trigger an eBPF multiplication integer overflow with a resultant
    out-of-bounds write (bnc#1191317).
  o CVE-2021-42008: Fixed a slab out-of-bounds write in the decode_data
    function in drivers/net/hamradio/6pack.c. Input from a process that had the
    CAP_NET_ADMIN capability could have lead to root access (bsc#1191315).
  o CVE-2021-37159: Fixed use-after-free and a double free in
    hso_free_net_device in drivers/net/usb/hso.c when unregister_netdev is
    called without checking for the NETREG_REGISTERED state (bnc#1188601).
