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

3. Description:

The kernel packages contain the Linux kernel, the core of any Linux operating
system.

Security Fix(es):

* kernel: bpf: Incorrect verifier pruning leads to unsafe code paths being
incorrectly marked as safe (CVE-2023-2163)

* kernel: tun: bugs for oversize packet when napi frags enabled in
tun_napi_alloc_frags (CVE-2023-3812)

* kernel: use after free in nvmet_tcp_free_crypto in NVMe (CVE-2023-5178)

* kernel: use-after-free due to race condition occurring in
dvb_register_device() (CVE-2022-45884)

* kernel: use-after-free due to race condition occurring in dvb_net.c
(CVE-2022-45886)

* kernel: use-after-free due to race condition occurring in dvb_ca_en50221.c
(CVE-2022-45919)

* kernel: use-after-free in smb2_is_status_io_timeout() (CVE-2023-1192)

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):

* Random delay receiving packets after bringing up VLAN on top of VF with vf-
vlan-pruning enabled (BZ#2240750)

* bpf_jit_limit hit again (BZ#2243011)

* HPE Edgeline 920t resets during kdump context when ice driver is loaded and
when system is booted with intel_iommu=on iommu=pt (BZ#2244625)

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.
