high Nessus Plugin ID 260468

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-2025:15016 advisory.

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

Security Fix(es):

* kernel: s390/ptrace: handle setting of fpc register correctly (CVE-2023-52598)

* kernel: USB: core: Fix deadlock in port disable sysfs attribute (CVE-2024-26933)

* kernel: powerpc/powernv: Add a null pointer check in opal_event_init() (CVE-2023-52686)

* kernel: mmc: sdio: fix possible resource leaks in some error paths (CVE-2023-52730)

* kernel: USB: core: Fix access violation during port device removal (CVE-2024-36896)

* kernel: pinctrl: fix deadlock in create_pinctrl() when handling -EPROBE_DEFER (CVE-2024-42090)

* kernel: bpf, test_run: Fix use-after-free issue in eth_skb_pkt_type() (CVE-2025-21867)

* kernel: crypto: algif_hash - fix double free in hash_accept (CVE-2025-38079)

* kernel: sch_hfsc: make hfsc_qlen_notify() idempotent (CVE-2025-38177)

* kernel: net/sched: Always pass notifications when child class becomes empty (CVE-2025-38350)

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-2025:15016.
