The following security bugs were fixed:


CVE-2022-29900, CVE-2022-29901: Fixed the RETBLEED attack, a new Spectre
 like Branch Target Buffer attack, that can leak arbitrary kernel
 information (bsc#1199657).

CVE-2022-34918: Fixed a buffer overflow with nft_set_elem_init() that
 could be used by a local attacker to escalate privileges (bnc#1201171).

CVE-2021-26341: Some AMD CPUs may transiently execute beyond
 unconditional direct branches, which may potentially result in data
 leakage (bsc#1201050).

CVE-2022-20154: Fixed a use after free due to a race condition in
 lock_sock_nested of sock.c. This could lead to local escalation of
 privilege with System execution privileges needed (bsc#1200599).

CVE-2022-2318: Fixed a use-after-free vulnerability in the timer
 handler in net/rose/rose_timer.c that allow attackers to crash the
 system without any privileges (bsc#1201251).

CVE-2022-1462: Fixed an out-of-bounds read flaw in the TeleTYpe
 subsystem (bnc#1198829).

CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742: Fixed
 multiple potential data leaks with Block and Network devices when using
 untrusted backends (bsc#1200762).

CVE-2022-33743: Fixed a Denial of Service related to XDP (bsc#1200763).

CVE-2022-1679: Fixed a use-after-free in the Atheros wireless driver in
 the way a user forces the ath9k_htc_wait_for_target function to fail
 with some input messages (bnc#1199487).

CVE-2022-20132: Fixed out of bounds read due to improper input
 validation in lg_probe and related functions of hid-lg.c (bnc#1200619).

CVE-2022-33981: Fixed use-after-free in floppy driver (bsc#1200692)

CVE-2022-1012: Fixed information leak caused by small table perturb size
 in the TCP source port generation algorithm (bsc#1199482).

CVE-2022-1998: Fixed a use after free in the file system notify
 functionality (bnc#1200284).

CVE-2022-1966: Fixed a use-after-free vulnerability in the Netfilter
 subsystem. This flaw allowed a local attacker with user access to cause
 a privilege escalation issue. (bnc#1200015)

CVE-2022-1852: Fixed a null-ptr-deref in the kvm module which can lead
 to DoS. (bsc#1199875)

CVE-2022-1789: Fixed a NULL pointer dereference when shadow paging is
 enabled. (bnc#1199674)

CVE-2022-1508: Fixed an out-of-bounds read flaw that could cause the
 system to crash. (bsc#1198968)

CVE-2022-1671: Fixed a null-ptr-deref bugs in net/rxrpc/server_key.c,
 unprivileged users could easily trigger it via ioctl. (bsc#1199439)

CVE-2022-1651: Fixed a bug in ACRN Device Model emulates virtual NICs in
 VM. This flaw may allow a local privileged attacker to leak kernel
 unauthorized information and also cause a denial of service problem.
 (bsc#1199433)

CVE-2022-29582: Fixed a use-after-free due to a race condition in
 io_uring timeouts. This can be triggered by a local user who has no
 access to any user namespace, ... [Please see the references for more information on the vulnerabilities]");
