high Nessus Plugin ID 277065

Synopsis

The remote Red Hat host is missing one or more security updates for kernel.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2025:22405 advisory.

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

Security Fix(es):

* kernel: nfsd: handle get_client_locked() failure in nfsd4_setclientid_confirm() (CVE-2025-38724)

* kernel: wifi: cfg80211: fix use-after-free in cmp_bss() (CVE-2025-39864)

* kernel: e1000e: fix heap overflow in e1000_set_eeprom (CVE-2025-39898)

* kernel: wifi: mt76: fix linked list corruption (CVE-2025-39918)

* kernel: tcp: Clear tcp_sk(sk)->fastopen_rsk in tcp_disconnect() (CVE-2025-39955)

* kernel: Bluetooth: MGMT: Fix possible UAFs (CVE-2025-39981)

* kernel: iommu/vt-d: Disallow dirty tracking if incoherent page walk (CVE-2025-40058)

* kernel: ice: ice_adapter: release xa entry on adapter allocation failure (CVE-2025-40185)

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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

Update the RHEL kernel package based on the guidance in RHSA-2025:22405.
