  <description>The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2022-1016: Fixed a vulnerability in the nf_tables component of the netfilter subsystem. This vulnerability gives an attacker a powerful primitive that can be used to both read from and write to relative stack data, which can lead to arbitrary code execution. (bsc#1197227)
- CVE-2022-1048: Fixed a race Condition in snd_pcm_hw_free leading to use-after-free due to the AB/BA lock with buffer_mutex and mmap_lock. (bsc#1197331)
- CVE-2022-0850: Fixed a kernel information leak vulnerability in iov_iter.c. (bsc#1196761)
- CVE-2021-45868: Fixed a wrong validation check in fs/quota/quota_tree.c which could lead to an use-after-free if there is a corrupted quota file. (bnc#1197366)
- CVE-2022-26966: Fixed an issue in drivers/net/usb/sr9700.c, which allowed attackers to obtain sensitive information from the memory via crafted frame lengths from a USB device. (bsc#1196836)
- CVE-2022-23036,CVE-2022-23037,CVE-2022-23038,CVE-2022-23039,CVE-2022-23040,CVE-2022-23041,CVE-2022-23042: Fixed multiple issues which could have lead to read/write access to memory pages or denial of service. These issues are related to the Xen PV device frontend drivers. (bsc#1196488)
- CVE-2022-26490: Fixed a buffer overflow in the st21nfca driver. An attacker with adjacent NFC access could crash the system or corrupt the system memory. (bsc#1196830)

The following non-security bugs were fixed:

- ax88179_178a: Merge memcpy + le32_to_cpus to get_unaligned_le32 (bsc#1196018).
- llc: fix netdevice reference leaks in llc_ui_bind() (git-fixes).
- net: usb: ax88179_178a: Fix out-of-bounds accesses in RX fixup (bsc#1196018).
- net: usb: ax88179_178a: fix packet alignment padding (bsc#1196018).
- sched/autogroup: Fix possible Spectre-v1 indexing for (git-fixes)
- sr9700: sanity check for packet length (bsc#1196836).
- usb: host: xen-hcd: add missing unlock in error path (git-fixes).
- xen/usb: do not use gnttab_end_foreign_access() in xenhcd_gnttab_done() (bsc#1196488, XSA-396).
