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).



The following non-security bugs were fixed:

IB/hfi1: Fix abba locking issue with sc_disable() (git-fixes)

KVM: PPC: Book3S HV: Save host FSCR in the P7/8 path (bsc#1065729).

NFS: Do uncached readdir when we're seeking a cookie in an empty page
 cache (bsc#1191628).

NFS: Fix backport error - dir_cookie is a pointer to a u64, not a u64.

PM: base: power: do not try to use non-existing RTC for storing data
 (git-fixes).

SMB3.1.1: Fix ids returned in POSIX query dir (bsc#1190317).

SMB3.1.1: do not log warning message if server does not populate salt
 (bsc#1190317).

SMB3.1.1: fix mount failure to some servers when compression enabled
 (bsc#1190317).

SMB3.1.1: remove confusing mount warning when no SPNEGO info on negprot
 rsp (bsc#1190317).

SMB3.1.1: update comments ... [Please see the references for more information on the vulnerabilities]");
