Summary
Red Hat Security Advisory: kernel-rt security update
Notes
Topic
An update for kernel-rt is now available for Red Hat Enterprise Linux 9.2 Extended Update Support.
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: netfilter: nf_tables: use timestamp to check for set element timeout (CVE-2024-27397)
* kernel: xen-netfront: Add missing skb_mark_for_recycle (CVE-2024-27393)
* kernel: netfilter: nft_flow_offload: reset dst in route object after setting up flow (CVE-2024-27403)
* kernel: smb: client: fix UAF in smb2_reconnect_server() (CVE-2024-35870)
* kernel: net/mlx5: Properly link new fs rules into the tree (CVE-2024-35960)
* kernel: net: ena: Fix incorrect descriptor free behavior (CVE-2024-35958)
* kernel: net: hns3: do not allow call hns3_nic_net_open repeatedly (CVE-2021-47400)
* kernel: octeontx2-af: avoid off-by-one read from userspace (CVE-2024-36957)
