Summary
Red Hat Security Advisory: kernel-rt security and bug fix update
Notes
Topic
An update for kernel-rt 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.
Details
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: bluetooth: Unauthorized management command execution (CVE-2023-2002)
* kernel: UAF in nftables when nft_set_lookup_global triggered after handling
named and anonymous sets in batch requests (CVE-2023-3390)
* kernel: cls_flower: out-of-bounds write in fl_set_geneve_opt()
(CVE-2023-35788)
* hw: amd: Cross-Process Information Leak (CVE-2023-20593,zenbleed)
* kernel: ipvlan: out-of-bounds write caused by unclear skb->cb (CVE-2023-3090)
* kernel: nf_tables: stack-out-of-bounds-read in nft_byteorder_eval()
(CVE-2023-35001,ZDI-CAN-20721)
* 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)
Bug Fix(es):
* kernel-rt: update RT source tree to the RHEL-8.8.z3 source tree (BZ#2227068)
* pods get restarted due to failed probes (BZ#2227238)

"text": "Only local users with `CAP_NET_ADMIN` capability or root can trigger this issue. \nOn Red Hat Enterprise Linux, local unprivileged users can exploit unprivileged user namespaces (CONFIG_USER_NS) to grant themselves this capability.\n\nThe OpenShift Container Platform (OCP) control planes or master machines are based on Red Hat Enterprise Linux CoreOS (RHCOS) that consists primarily of RHEL components, therefore, it is also affected by this kernel vulnerability. A successful exploit needs necessary privileges (CAP_NET_ADMIN) and direct, local access. A local user in RHCOS is already a root with full permissions, hence existence of this vulnerability does not bring any value from the potential attacker perspective. From the OpenShift containers perspective, this vulnerability cannot be exploited as in OpenShift the cluster processes on the node are namespaced, which means that switching the namespace in the running OpenShift container will not bring necessary capabilities.\nThis means that for OpenShift, the impact of this vulnerability is Low.\n\nSimilar to the CVE-2023-32233 vulnerability, this has been explained in the following blog post as an example of a \"Container escape vulnerability\":\nhttps://www.redhat.com/en/blog/containers-vulnerability-risk-assessment",
