This kernel update is based on upstream 5.15.35 and fixes at least the following security issues:

A denial of service (DOS) issue was found in the Linux kernel smb2_ioctl_query_info function in the fs/cifs/smb2ops.c Common Internet File System (CIFS) due to an incorrect return from the memdup_user function. This flaw allows a local, privileged (CAP_SYS_ADMIN) attacker to crash the system (CVE-2022-0168).

x86/kvm: cmpxchg_gpte can write to pfns outside the userspace region (CVE-2022-1158).

A use-after-free vulnerabilities in drivers/net/hamradio/6pack.c allow attacker to crash linux kernel by simulating Amateur Radio from user-space (CVE-2022-1198).

A use-after-free flaw was found in the Linux kernel’s Amateur Radio AX.25 protocol functionality in the way a user connects with the protocol. This flaw allows a local user to crash the system (CVE-2022-1204).

A NULL pointer dereference flaw was found in the Linux kernel’s Amateur Radio AX.25 protocol functionality in the way a user connects with the protocol. This flaw allows a local user to crash the system (CVE-2022-1205).

A null pointer dereference was found in the kvm module which can lead to denial of service (CVE-2022-1263).

A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a leak of internal kernel information (CVE-2022-1353).

usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c in the Linux kernel through 5.17.1 has a double free (CVE-2022-28388).

mcba_usb_start_xmit in drivers/net/can/usb/mcba_usb.c in the Linux kernel through 5.17.1 has a double free (CVE-2022-28389).

ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free (CVE-2022-28390).

In the Linux kernel before 5.17.3, fs/io_uring.c has a use-after-free due to a race condition in io_uring timeouts. This can be triggered by a local user who has no access to any user namespace (CVE-2022-29582).

Other fixes in this update:

• gpio: Request interrupts after IRQ is initialized
• net: atlantic: invert deep par in pm functions, preventing null derefs
• xtables-addons have been updated to 3.20

These are all security issues fixed in the kernel-devel-5.17.2-1.1 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the kernel-devel-longterm-6.6.17-1.1 package on the GA media of openSUSE Tumbleweed.

The SUSE Linux Enterprise 15 SP3 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

• 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-2022-1016: 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)
