AlmaLinux 9.2 [TuxCare] Security Update: qemu-guest-agent / qemu-img / qemu-kvm / qemu-kvm-audio-pa / etc Multiple Vulnerabilities (ALMALINUX9.2:CLSA-2025:1761673460)

high Nessus Plugin ID 360130

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2025:1761673460 advisory.

- A double free vulnerability was found in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio- crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. This issue could allow a malicious privileged guest user to crash the QEMU process on the host, resulting in a denial of service or allow arbitrary code execution within the context of the QEMU process on the host.
(CVE-2024-3446)

- A flaw was found in the QEMU disk image utility (qemu-img) 'info' command. A specially crafted image file containing a `json:{}` value describing block devices in QMP could cause the qemu-img process on the host to consume large amounts of memory or CPU time, leading to denial of service or read/write to an existing external file. (CVE-2024-4467)

- A flaw was found in the QEMU NBD Server. This vulnerability allows a denial of service (DoS) attack via improper synchronization during socket closure when a client keeps a socket open as the server is taken offline. (CVE-2024-7409)

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 based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2025:1761673460.
