SUSE-SU-2022:1197-1

The SUSE Linux Enterprise 15 SP2 kernel was updated.

The following security bugs were fixed:

• 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-2022-27666: Fixed a buffer overflow vulnerability in IPsec ESP transformation code. This flaw allowed a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation. (bnc#1197462)
• CVE-2022-0850: Fixed a kernel information leak vulnerability in iov_iter.c. (bsc#1196761)
• CVE-2022-1055: Fixed a use-after-free in tc_new_tfilter that could allow a local attacker to gain privilege escalation. (bnc#1197702)
• 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-2022-28390: Fixed a double free in drivers/net/can/usb/ems_usb.c vulnerability in the Linux kernel. (bnc#1198031)
• CVE-2022-28388: Fixed a double free in drivers/net/can/usb/usb_8dev.c vulnerability in the Linux kernel. (bnc#1198032)
• CVE-2022-28389: Fixed a double free in drivers/net/can/usb/mcba_usb.c vulnerability in the Linux kernel. (bnc#1198033)
• 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-2022-0854: Fixed a memory leak flaw was found in the Linux kernels DMA subsystem. This flaw allowed a local user to read random memory from the kernel space. (bnc#1196823)
• 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-2021-39698: Fixed a possible memory corruption due to a use after free in aio_poll_complete_work. This could lead to local escalation of privilege with no additional execution privileges needed. (bsc#1196956)
• CVE-2021-0920: Fixed a race condition during UNIX socket garbage collection that could lead to local privilege escalation. (bsc#119373)
• 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).
• cifs: use the correct max-length for dentry_path_raw() (bsc1196196).
• drm: add a locked version of drm_is_current_master (bsc#1197914).
• drm: drm_file struct kABI compatibility workaround (bsc#1197914).
• drm: protect drm_master pointers in drm_lease.c (bsc#1197914).
• drm: serialize drm_file.master with a new spinlock (bsc#1197914).
• drm: use the lookup lock in drm_is_current_master (bsc#1197914).
• net: tipc: validate domain record count on input (bsc#1195254).
• 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/mlx5e: Fix page DMA map/unmap attributes (bsc#1196468).
• netfilter: conntrack: do not refresh sctp entries in closed state (bsc#1197389).
• powerpc/mm/numa: skip NUMA_NO_NODE onlining in parse_numa_properties() (bsc#1179639 ltc#189002 git-fixes).
• SUNRPC: avoid race between mod_timer() and del_timer_sync() (bnc#1195403).
• 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).
