(RHSA-2022:7444) Moderate: kernel-rt security and bug fix update

Description

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. 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) * NULL pointer dereference in udf_expand_file_adinicbdue() during writeback (CVE-2022-0617) * 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) * 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) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
