Summary
Important: kernel security, bug fix, and enhancement update
Details

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

  • kernel: ipvlan: Make the addrs_lock be per port (CVE-2026-23103)

  • kernel: KVM: SEV: Require in-GHCB scratch area if GHCB v2+ is in use (CVE-2026-53360)

  • kernel: vsock/virtio: fix zerocopy completion for multi-skb sends (CVE-2026-53365)

  • kernel: NFSD: Fix SECINFO_NO_NAME decode error cleanup (CVE-2026-53398)

  • kernel: vsock/virtio: bind uarg before filling zerocopy skb (CVE-2026-63970)

  • kernel: igc: set tx buffer type for SMD frames (CVE-2026-64035)

  • kernel: idpf: fix read_dev_clk_lock spinlock init in idpf_ptp_init() (CVE-2026-64162)

  • kernel: vsock/vmci: fix UAF when peer resets connection during handshake (CVE-2026-64115)

  • kernel: SUNRPC: pin upper rpc_clnt across the TLS connect_worker (CVE-2026-72317)

  • kernel: ipvlan: inherit needed_headroom and needed_tailroom from phy_dev (CVE-2026-74744)

  • kernel: nfsd: defer vfree of compound ops to fix rpc_status UAF (CVE-2026-89690)

  • kernel: nfsd: initialize copy-notify stateid before publishing it (CVE-2026-89669)

  • kernel: svcrdma: Reject inline replies that overflow the pull-up buffer (CVE-2026-89530)

  • kernel: nfsd: revoke copy-notify stateids before dropping their reference (CVE-2026-89663)

Bug Fix(es) and Enhancement(s):

  • "iavf: refactor iavf_clean_rx_irq to support legacy and flex descriptors" broke rx-vlan-offload on rhel-9.7 [rhel-9.8.z] (JIRA:Rocky Linux-169480)

  • [GNR-D] missing interfaces tspll_cfg (JIRA:Rocky Linux-183201)

  • Rocky Linux9.8z KVM guest panicked in vmmouse driver (JIRA:Rocky Linux-186577)

  • Add Epson RX8111 support to Rocky Linux9.9 [rhel-9.8.z] (JIRA:Rocky Linux-212014)

  • RT scheduler livelock: migrate-disabled task at pushable-list head causes repeated RT push/stopper retries, starving a critical RT task (remaining issue after CVE-2026-45919 fix in 94894c9c477e) [rhel-9.8.z] (JIRA:Rocky Linux-256279)
