Summary
Red Hat Security Advisory: kernel-rt security update
Notes
Topic
An update for kernel-rt is now available for Red Hat Enterprise Linux 8.2 Advanced Update Support, Red Hat Enterprise Linux 8.2 Telecommunications Update Service, and Red Hat Enterprise Linux 8.2 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):
* kernel: use-after-free in smb2_is_status_io_timeout() (CVE-2023-1192)
* kernel: vmxnet3: NULL pointer dereference in vmxnet3_rq_cleanup() (CVE-2023-4459)
* kernel: tun: bugs for oversize packet when napi frags enabled in tun_napi_alloc_frags (CVE-2023-3812)
* kernel: refcount leak in ctnetlink_create_conntrack() (CVE-2023-7192)
* kernel: mlxsw: spectrum_acl_tcam: Fix stack corruption (CVE-2024-26586)
* kernel: netfilter: divide error in nft_limit_init (CVE-2021-46915)
* kernel: sched/membarrier: reduce the ability to hammer on sys_membarrier (CVE-2024-26602)

"details": "Triggering this issue requires the ability to create user/net namespaces.\n\nOn non-containerized deployments of Red Hat Enterprise Linux 8, you can disable user namespaces by setting user.max_user_namespaces to 0:\n\n# echo \"user.max_user_namespaces=0\" \u003e /etc/sysctl.d/userns.conf\n# sysctl -p /etc/sysctl.d/userns.conf\n\nOn containerized deployments, such as Red Hat OpenShift Container Platform, do not use this mitigation as the functionality is needed to be enabled.\n\nAlternatively, skip loading the affected netfilter module (i.e., nf_conntrack_netlink) onto the system until we have a fix available. 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~~~",
