Important: kernel-rt security update
Type: advisorySources: OSV
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: vsock/vmci: fix UAF when peer resets connection during handshake (CVE-2026-64115) * kernel: packet: use consistent hard_header_len in non-ring send paths () * kernel: packet: use consistent hard_header_len in non-ring send paths (CVE-2026-74582) * kernel: svcrdma: Reject inline replies that overflow the pull-up buffer (CVE-2026-89530) 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.
