An update that solves 20 vulnerabilities, contains one feature and has three
fixes is now available.

Description:

The SUSE Linux Enterprise 15 kernel was updated to receive various security and
bugfixes.
The following security bugs were fixed:

  o CVE-2022-28356: Fixed a refcount leak bug in net/llc/af_llc.c (bnc#
    1197391).
  o 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).
  o CVE-2022-28389: Fixed a double free in drivers/net/can/usb/mcba_usb.c
    vulnerability in the Linux kernel (bnc#1198033).
  o CVE-2022-28388: Fixed a double free in drivers/net/can/usb/usb_8dev.c
    vulnerability in the Linux kernel (bnc#1198032).
  o CVE-2022-28390: Fixed a double free in drivers/net/can/usb/ems_usb.c
    vulnerability in the Linux kernel (bnc#1198031).
  o CVE-2022-0812: Fixed an incorrect header size calculations in xprtrdma (bsc
    #1196639).
  o 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).
  o CVE-2022-0850: Fixed a kernel information leak vulnerability in iov_iter.c
    (bsc#1196761).
  o 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).
  o CVE-2022-0886: Fix possible buffer overflow in ESP transformation (bsc#
    1197131).
  o 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).
  o CVE-2021-39713: Fixed a race condition in the network scheduling subsystem
    which could lead to a use-after-free (bsc#1196973). -

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:

  o ax88179_178a: Merge memcpy + le32_to_cpus to get_unaligned_le32 (bsc#
    1196018).
  o macros.kernel-source: Fix coditional expansion. Fixes: bb95fef3cf19 ("rpm:
    Use bash for %() expansion (jsc#SLE-18234).")
  o net: usb: ax88179_178a: Fix out-of-bounds accesses in RX fixup (bsc#
    1196018).
  o net: usb: ax88179_178a: fix packet alignment padding (bsc#1196018).
  o net/mlx5e: Fix page DMA map/unmap attributes (bsc#1196468).
  o rpm: SC2006: Use $(...) notation instead of legacy backticked `...`.
  o sr9700: sanity check for packet length (bsc#1196836).
  o usb: host: xen-hcd: add missing unlock in error path (git-fixes).
  o xen/usb: do not use gnttab_end_foreign_access() in xenhcd_gnttab_done()
    (bsc#1196488, XSA-396).
