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

The following security bugs were fixed:

CVE-2021-3655: Fixed a missing size validations on inbound SCTP packets,
which may have allowed the kernel to read uninitialized memory
(bsc#1188563).
CVE-2021-3715: Fixed a use-after-free in route4_change() in
net/sched/cls_route.c (bsc#1190349).
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).
CVE-2021-3760: Fixed a use-after-free vulnerability with the
ndev->rf_conn_info object (bsc#1190067).
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).
CVE-2021-3542: Fixed heap buffer overflow in firedtv driver
(bsc#1186063).
CVE-2021-34556: Fixed side-channel attack via a Speculative Store Bypass
via unprivileged BPF program that could have obtain sensitive
information from kernel memory (bsc#1188983).
CVE-2021-35477: Fixed BPF stack frame pointer which could have been
abused to disclose content of arbitrary kernel memory (bsc#1188985).
CVE-2021-42252: Fixed an issue inside aspeed_lpc_ctrl_mmap that could
have allowed local attackers to access the Aspeed LPC control interface
to overwrite memory in the kernel and potentially execute privileges
(bnc#1190479).
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).
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).
CVE-2021-37159: Fixed use-after-free and a double free inside
hso_free_net_device in drivers/net/usb/hso.c when unregister_netdev is
called without checking for the NETREG_REGISTERED state (bnc#1188601).
