Security Fix(es): * kernel: netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeout (CVE-2024-26643) * kernel: netfilter: nf_tables: disallow anonymous set with timeout flag (CVE-2024-26642) * kernel: netfilter: nft_ct: sanitize layer 3 and 4 protocol number in custom expectations (CVE-2024-26673) * kernel: ipv6: sr: fix possible use-after-free and null-ptr-deref (CVE-2024-26735) * kernel: net: ip_tunnel: prevent perpetual headroom growth (CVE-2024-26804) * kernel: cifs: fix underflow in parse_server_interfaces() (CVE-2024-26828) * kernel: fs: sysfs: Fix reference leak in sysfs_break_active_protection() (CVE-2024-26993) Bug Fix(es): * lan78xx changes for 9.2.z, to fix link speed change exception and other bug fixes (JIRA:RHEL-34926) 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.

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

This advisory addresses multiple moderate-severity vulnerabilities in the Linux kernel packages used by Red Hat Enterprise Linux 9. The issues involve netfilter nf_tables handling of anonymous sets with timeout flags, sanitization of protocol numbers in custom expectations, and prevention of perpetual headroom growth in IP tunnels. These vulnerabilities could affect kernel stability and security. Red Hat has released an update that fixes these issues, and a system reboot is required to apply the update.
