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 8.4 Advanced Mission Update Support, Red Hat Enterprise Linux 8.4 Telecommunications Update Service, and Red Hat Enterprise Linux 8.4 Update Services for SAP Solutions.
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):
* vmwgfx: NULL pointer dereference in vmw_cmd_dx_define_query (CVE-2022-38096)
* null-ptr-deref vulnerabilities in sl_tx_timeout in drivers/net/slip (CVE-2022-41858)
* nfp: use-after-free in area_cache_get() (CVE-2022-3545)
* NULL pointer dereference in can_rcv_filter (CVE-2023-2166)
* Slab-out-of-bound read in compare_netdev_and_ip (CVE-2023-2176)
* out-of-bounds write in qfq_change_class function (CVE-2023-31436)
* NULL pointer dereference in vmxnet3_rq_cleanup() (CVE-2023-4459)
* net/sched: sch_qfq component can be exploited if in qfq_change_agg function happens qfq_enqueue overhead (CVE-2023-3611)
* ktls overwrites readonly memory pages when using function splice with a ktls socket as destination (CVE-2024-0646)
* inactive elements in nft_pipapo_walk (CVE-2023-6817)
* refcount leak in ctnetlink_create_conntrack() (CVE-2023-7192)

* null-ptr-deref vulnerabilities in sl_tx_timeout in drivers/net/slip (JIRA:RHEL-19023)
* Slab-out-of-bound read in compare_netdev_and_ip (JIRA:RHEL-19404)
* A flaw leading to a use-after-free in area_cache_get() (JIRA:RHEL-19530)
* vmxgfx: NULL pointer dereference in vmw_cmd_dx_define_query (JIRA:RHEL-22755)
* NULL pointer dereference in can_rcv_filter (JIRA:RHEL-19520)

"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",

This can be done by a blacklist mechanism which will ensure the driver is not loaded at boot time.\n~~~\nHow do I blacklist a kernel module to prevent it from loading automatically?\nhttps://access.redhat.com/solutions/41278 \n~~~",
