The following security bugs were fixed:
CVE-2018-9517: Fixed possible memory corruption due to a use after free
in pppol2tp_connect (bsc#1108488).
CVE-2019-3874: Fixed possible denial of service attack via SCTP socket
buffer used by a userspace applications (bnc#1129898).
CVE-2019-3900: Fixed an infinite loop issue while handling incoming
packets in handle_rx() (bnc#1133374).
CVE-2021-3640: Fixed a Use-After-Free vulnerability in function
sco_sock_sendmsg() in the bluetooth stack (bsc#1188172).
CVE-2021-3653: Missing validation of the `int_ctl` VMCB field and allows
a malicious L1 guest to enable AVIC support for the L2 guest.
(bsc#1189399).
CVE-2021-3656: Missing validation of the `virt_ext` VMCB field and
allows a malicious L1 guest to disable both VMLOAD/VMSAVE intercepts and
VLS for the L2 guest (bsc#1189400).
CVE-2021-3679: A lack of CPU resource in tracing module functionality
was found in the way user uses trace ring buffer in a specific way. Only
privileged local users (with CAP_SYS_ADMIN capability) could use this
flaw to starve the resources causing denial of service (bnc#1189057).
CVE-2021-3732: Mounting overlayfs inside an unprivileged user namespace
can reveal files (bsc#1189706).
CVE-2021-3753: Fixed race out-of-bounds in virtual terminal handling
(bsc#1190025).
CVE-2021-3759: Unaccounted ipc objects in Linux kernel could have lead
to breaking memcg limits and DoS attacks (bsc#1190115).
CVE-2021-38160: Data corruption or loss could be triggered by an
untrusted device that supplies a buf->len value exceeding the buffer
size in drivers/char/virtio_console.c (bsc#1190117)
CVE-2021-38198: arch/x86/kvm/mmu/paging_tmpl.h incorrectly computes the
access permissions of a shadow page, leading to a missing guest
protection page fault (bnc#1189262).
CVE-2021-38204: drivers/usb/host/max3421-hcd.c allowed physically
proximate attackers to cause a denial of service (use-after-free and
panic) by removing a MAX-3421 USB device in certain situations
(bnc#1189291).
The following non-security bugs were fixed:
ACPI: NFIT: Fix support for virtual SPA ranges (git-fixes).
ALSA: seq: Fix racy deletion of subscriber (git-fixes).
ASoC: cs42l42: Do not allow SND_SOC_DAIFMT_LEFT_J (git-fixes).
ASoC: cs42l42: Fix inversion of ADC Notch Switch control (git-fixes).
ASoC: cs42l42: Remove duplicate control for WNF filter frequency
(git-fixes).
Bluetooth: Move shutdown callback before flushing tx and rx queue
(git-fixes).
Bluetooth: add timeout sanity check to hci_inquiry (git-fixes).
Bluetooth: fix repeated calls to sco_sock_kill (git-fixes).
Bluetooth: increase BTNAMSIZ to 21 chars to fix potential buffer
overflow (git-fixes).
Bluetooth: sco: prevent information leak in sco_conn_defer_accept()
(git-fixes).
