The following security bugs were fixed:
CVE-2021-3347: A use-after-free was discovered in the PI futexes during
fault handling, allowing local users to execute code in the kernel
(bnc#1181349).
CVE-2021-3348: Fixed a use-after-free in nbd_add_socket that could be
triggered by local attackers (with access to the nbd device) via an I/O
request at a certain point during device setup (bnc#1181504).
CVE-2021-20177: Fixed a kernel panic related to iptables string matching
rules. A privileged user could insert a rule which could lead to denial
of service (bnc#1180765).
CVE-2021-0342: In tun_get_user of tun.c, there is possible memory
corruption due to a use after free. This could lead to local escalation
of privilege with System execution privileges required. (bnc#1180812)
CVE-2020-27835: A use-after-free in the infiniband hfi1 driver was
found, specifically in the way user calls Ioctl after open dev file and
fork. A local user could use this flaw to crash the system (bnc#1179878).
CVE-2020-25639: Fixed a NULL pointer dereference via nouveau ioctl
(bnc#1176846).
CVE-2020-29569: Fixed a potential privilege escalation and information
leaks related to the PV block backend, as used by Xen (bnc#1179509).
CVE-2020-29568: Fixed a denial of service issue, related to processing
watch events (bnc#1179508).
CVE-2020-25211: Fixed a flaw where a local attacker was able to inject
conntrack netlink configuration that could cause a denial of service or
trigger the use of incorrect protocol numbers in
ctnetlink_parse_tuple_filter (bnc#1176395).
The following non-security bugs were fixed:
ACPI/IORT: Do not blindly trust DMA masks from firmware (git-fixes).
ACPI: scan: add stub acpi_create_platform_device() for !CONFIG_ACPI
(git-fixes).
ACPI: scan: Harden acpi_device_add() against device ID overflows
(git-fixes).
ACPI: scan: Make acpi_bus_get_device() clear return pointer on error
(git-fixes).
ACPI: sysfs: Prefer 'compatible' modalias (git-fixes).
ALSA: doc: Fix reference to mixart.rst (git-fixes).
ALSA: fireface: Fix integer overflow in transmit_midi_msg() (git-fixes).
ALSA: firewire-tascam: Fix integer overflow in midi_port_work()
(git-fixes).
ALSA: hda: Add Cometlake-R PCI ID (git-fixes).
ALSA: hda/conexant: add a new hda codec CX11970 (git-fixes).
ALSA: hda/hdmi - enable runtime pm for CI AMD display audio (git-fixes).
ALSA: hda/realtek: Add mute LED quirk for more HP laptops (git-fixes).
ALSA: hda/realtek: Add two 'Intel Reference board' SSID in the ALC256
(git-fixes).
ALSA: hda/realtek: Enable headset of ASUS B1400CEPE with ALC256
(git-fixes).
ALSA: hda/realtek: Enable mute and micmute LED on HP EliteBook 850 G7
(git-fixes).
ALSA: hda/realtek: fix right sounds and mute/micmute LEDs for HP
machines (git-fixes).
ALSA: hda/realtek - Fix speaker ... [Please see the references for more information on the vulnerabilities]");
