1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 8.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat CodeReady Linux Builder (v. 8) - aarch64, ppc64le, x86_64
Red Hat Enterprise Linux BaseOS (v. 8) - aarch64, noarch, ppc64le, s390x, x86_64

3. Description:

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)

(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)

* 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)
