NOTE: This update was retracted due to a NFS regression.

The following security bugs were fixed:

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

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-2021-43056: Fixed possible KVM host crash via malicious KVM guest on
 Power8 (bnc#1192107).

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

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-2021-33033: 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-2021-3715: Fixed a use-after-free in route4_change() in
 net/sched/cls_route.c (bsc#1190349).

CVE-2021-34866: Fixed eBPF Type Confusion Privilege Escalation
 Vulnerability (bsc#1191645).

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).

The following non-security bugs were fixed:

ACPI: NFIT: Use fallback node id when numa info in NFIT table is
 incorrect (git-fixes).

ACPI: bgrt: Fix CFI violation (git-fixes).

ACPI: fix NULL pointer dereference (git-fixes).

ACPI: fix NULL pointer dereference (git-fixes).

ALSA: hda - Enable headphone mic on Dell Latitude laptops with ALC3254
 (git-fixes).

ALSA: hda/realtek - ALC236 headset MIC recording issue (git-fixes).

ALSA: hda/realtek: Add quirk for Clevo PC50HS (git-fixes).

ALSA: hda/realtek: Add quirk for Clevo X170KM-G (git-fixes).

ALSA: hda/realtek: Add quirk for TongFang PHxTxX1 (git-fixes).

ALSA: hda/realtek: Complete partial device name to avoid ambiguity
 (git-fixes).

ALSA: hda/realtek: Enable 4-speaker output for Dell Precision 5560
 laptop (git-fixes).

 13s Gen2 (git-fixes).
