1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 9.0
Extended Update Support.

Red Hat Product Security has rated this update as having a security impact
of Important. 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 EUS (v.9.0) - aarch64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux AppStream EUS (v.9.0) - aarch64, noarch, ppc64le, s390x, x86_64
Red Hat Enterprise Linux BaseOS EUS (v.9.0) - 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):

* kernel: use-after-free caused by l2cap_reassemble_sdu() in
net/bluetooth/l2cap_core.c (CVE-2022-3564)

* kernel: stack overflow in do_proc_dointvec and proc_skip_spaces
(CVE-2022-4378)

* kernel: use-after-free in __nfs42_ssc_open() in fs/nfs/nfs4file.c leading
to remote Denial of Service attack (CVE-2022-4379)

* kernel: Netfilter integer overflow vulnerability in nft_payload_copy_vlan
(CVE-2023-0179)

* ALSA: pcm: Move rwsem lock inside snd_ctl_elem_read to prevent UAF
(CVE-2023-0266)

* kernel: net: CPU soft lockup in TC mirred egress-to-ingress action
(CVE-2022-4269)

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.

Bug Fix(es):

* RHEL9:[P10] With Guest Secure Boot and lockdown enabled, DLPAR operations
can't be done (Rainier) (BZ#2107480)

* [RHEL 9.0] LTP Test failure and crash at fork14 on Sapphire Rapids
Platinum 8280+ (BZ#2133084)

* RHEL9.0 - boot: Add secure boot trailer (BZ#2151529)

* 'date' command shows wrong time in nested KVM s390x guest (BZ#2158816)

* Kernel FIPS-140-3 requirements - part 3 - AES-XTS (BZ#2160176)

* RHEL 9.0.0 soft quota cannot exceed more the 5 warns which breaks timer
functionality (BZ#2164263)

* In FIPS mode, the kernel should reject SHA-224, SHA-384, SHA-512-224, and
SHA-512-256 as hashes for hash-based DRBGs, or provide an indicator after
2023-05-16 (BZ#2165131)

* [RHEL 9] FIPS: deadlock between PID 1 and "modprobe
crypto-jitterentropy_rng" at boot, preventing system to boot. (BZ#2167762)

Enhancement(s):

* [Intel 9.2 FEAT] [SPR] CPU: AMX: Improve the init_fpstate setup code
(BZ#2168383)
