=====================================================================

1. Summary:

An update for kernel-rt is now available for Red Hat Enterprise Linux 9.

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 Enterprise Linux NFV (v. 9) - x86_64
Red Hat Enterprise Linux RT (v. 9) - x86_64

3. 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):

* kernel: UAF in nftables when nft_set_lookup_global triggered after
handling named and anonymous sets in batch requests (CVE-2023-3390)

* kernel: netfilter: nf_tables: fix chain binding transaction logic in the
abort path of NFT_MSG_NEWRULE (CVE-2023-3610)

* kernel: net/sched: cls_fw component can be exploited as result of failure
in tcf_change_indev function (CVE-2023-3776)

* kernel: netfilter: use-after-free due to improper element removal in
nft_pipapo_remove() (CVE-2023-4004)

* kernel: netfilter: nf_tables_newrule when adding a rule with
NFTA_RULE_CHAIN_ID leads to use-after-free (CVE-2023-4147)

* kernel: nf_tables: use-after-free in nft_chain_lookup_byid()
(CVE-2023-31248)

* kernel: nf_tables: stack-out-of-bounds-read in nft_byteorder_eval()
(CVE-2023-35001)

* kernel: save/restore speculative MSRs during S3 suspend/resume
(CVE-2023-1637)

* hw: amd: Cross-Process Information Leak (CVE-2023-20593)

* kernel: bypass of shadow stack protection due to a logic error
(CVE-2023-21102)

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):

* kernel-rt: update RT source tree to the latest RHEL-9.2.z3 Batch
(BZ#2228482)

4. Solution:

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.
