high Nessus Plugin ID 242143

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-2025:11245 advisory.

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

* kernel: ipv6: mcast: extend RCU protection in igmp6_send() (CVE-2025-21759)

* kernel: Squashfs: fix handling and sanity checking of xattr_ids count (CVE-2023-52933)

* kernel: net: atm: fix use after free in lec_send() (CVE-2025-22004)

* kernel: ext4: fix out-of-bound read in ext4_xattr_inode_dec_ref_all() (CVE-2025-22121)

* kernel: ext4: fix off-by-one error in do_split (CVE-2025-23150)

* kernel: ext4: ignore xattrs past end (CVE-2025-37738)

* kernel: net/mdiobus: Fix potential out-of-bounds clause 45 read/write access (CVE-2025-38110)

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-2025:11245.
