high Nessus Plugin ID 306523

Synopsis

The remote AlmaLinux host is missing one or more security updates.

Description

The remote AlmaLinux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2026:6632 advisory.

 * kernel: Linux kernel (net/mlx5): Use-after-free in ECVF vports unload leads to denial of service (CVE-2025-38109)
 * kernel: Linux kernel: Local denial of service and memory leak in DAMON sysfs via setup failure (CVE-2026-23144)

 * kernel: scsi: target: iscsi: Fix use-after-free in iscsit_dec_session_usage_count() (CVE-2026-23193)
 * kernel: macvlan: fix error recovery in macvlan_common_newlink() (CVE-2026-23209)
 * kernel: net/sched: cls_u32: use skb_header_pointer_careful() (CVE-2026-23204)
 * kernel: ALSA: aloop: Fix racy access at PCM trigger (CVE-2026-23191)

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

Update the affected packages.
