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 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.
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: 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)

"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",
