For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

The system must be rebooted for this update to take effect.

Summary

The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):
* off-path attacker may inject data or terminate victim's TCP session (CVE-2020-36516)
* race condition in VT_RESIZEX ioctl when vc_cons[i].d is already NULL leading to NULL pointer dereference (CVE-2020-36558)
* use-after-free vulnerability in function sco_sock_sendmsg() (CVE-2021-3640)
* memory leak for large arguments in video_usercopy function in drivers/media/v4l2-core/v4l2-ioctl.c (CVE-2021-30002)
* smb2_ioctl_query_info NULL Pointer Dereference (CVE-2022-0168)

* swiotlb information leak with DMA_FROM_DEVICE (CVE-2022-0854)
* uninitialized registers on stack in nft_do_chain can cause kernel pointer leakage to UM (CVE-2022-1016)
* race condition in snd_pcm_hw_free leading to use-after-free (CVE-2022-1048)
* use-after-free in tc_new_tfilter() in net/sched/cls_api.c (CVE-2022-1055)
* use-after-free and memory errors in ext4 when mounting and operating on a corrupted image (CVE-2022-1184)
* NULL pointer dereference in x86_emulate_insn may lead to DoS (CVE-2022-1852)
* buffer overflow in nft_set_desc_concat_parse() (CVE-2022-2078)
* nf_tables cross-table potential use-after-free may lead to local privilege escalation (CVE-2022-2586)
* openvswitch: integer underflow leads to out-of-bounds write in reserve_sfa_size() (CVE-2022-2639)
* use-after-free when psi trigger is destroyed while being polled (CVE-2022-2938)
* net/packet: slab-out-of-bounds access in packet_recvmsg() (CVE-2022-20368)
* possible to use the debugger to write zero into a location of choice (CVE-2022-21499)
* Spectre-BHB (CVE-2022-23960)
* Post-barrier Return Stack Buffer Predictions (CVE-2022-26373)
* memory leak in drivers/hid/hid-elo.c (CVE-2022-27950)
* double free in ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c (CVE-2022-28390)
* use after free in SUNRPC subsystem (CVE-2022-28893)
* use-after-free due to improper update of reference count in net/sched/cls_u32.c (CVE-2022-29581)
* DoS in nfqnl_mangle in net/netfilter/nfnetlink_queue.c (CVE-2022-36946)
* nfs_atomic_open() returns uninitialized data instead of ENOTDIR (CVE-2022-24448)
