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).
