   An update that fixes 13 vulnerabilities is now available.

Description:


   The SUSE Linux Enterprise 12 SP3 kernel was updated.

   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).
   - clocksource: Initialize cs->wd_list (git-fixes)
   - 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).
