Description

The remote AlmaLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2026:77689 advisory.

 * 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 almalinux-9.7 [almalinux-9.8.z] (JIRA:AlmaLinux-169480)
 * [GNR-D] missing interfaces tspll_cfg (JIRA:AlmaLinux-183201)
 * AlmaLinux9.8z KVM guest panicked in vmmouse driver (JIRA:AlmaLinux-186577)
 * Add Epson RX8111 support to AlmaLinux9.9 [almalinux-9.8.z] (JIRA:AlmaLinux-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) [almalinux-9.8.z] (JIRA:AlmaLinux-256279)

Tenable has extracted the preceding description block directly from the AlmaLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution
