high Nessus Plugin ID 292594

Synopsis

The remote MiracleLinux host is missing a security update.

Description

The remote MiracleLinux 7 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2025-10699:04 advisory.

* CVE-2025-6019: don't allow suid and dev set on fs resize CVE(s):
CVE-2025-6019 A Local Privilege Escalation (LPE) vulnerability was found in libblockdev. Generally, the allow_active setting in Polkit permits a physically present user to take certain actions based on the session type. Due to the way libblockdev interacts with the udisks daemon, an allow_active user on a system may be able escalate to full root privileges on the target host. Normally, udisks mounts user-provided filesystem images with security flags like nosuid and nodev to prevent privilege escalation. However, a local attacker can create a specially crafted XFS image containing a SUID-root shell, then trick udisks into resizing it. This mounts their malicious filesystem with root privileges, allowing them to execute their SUID-root shell and gain complete control of the system.

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

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

Solution

Update the affected packages.
