Detectable: no evidence on record.
No public nuclei template indexed

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade Red Hat to 8.10.0.

AI-suggested

Red Hat has released an official security update for the virt:rhel and virt-devel:rhel modules that addresses these vulnerabilities. Users should apply the update as described in the Red Hat advisory RHSA-2024:6964 and the referenced article https://access.redhat.com/articles/11258. This update fixes the double free, denial of service, and certificate validation issues. No additional mitigation steps are required beyond applying the official patch.

Description

Red Hat has issued a moderate security update for the virt:rhel and virt-devel:rhel modules in Red Hat Enterprise Linux 8. The update addresses three vulnerabilities: a double free vulnerability due to a DMA reentrancy issue in QEMU virtio (CVE-2024-3446), a denial of service caused by improper synchronization in the QEMU NBD server during socket closure (CVE-2024-7409), and improper certificate validation in the libnbd NBD server (CVE-2024-7383). These vulnerabilities affect user-space components used to run and manage virtual machines with KVM. The update is available for Red Hat Enterprise Linux 8 versions from 8.0.0 up to but not including 8.10.0 across multiple architectures including s390x. No known exploits in the wild have been reported. Users should apply the official Red Hat update to remediate these issues.

Impact

The vulnerabilities could lead to a double free condition potentially causing crashes or memory corruption (CVE-2024-3446), denial of service via improper synchronization (CVE-2024-7409), and security bypass due to improper certificate validation (CVE-2024-7383). These issues affect the stability and security of virtual machine management on affected Red Hat Enterprise Linux 8 systems. No known exploits in the wild have been reported, and the severity is rated moderate by Red Hat.

CWE-415Double Free (opens in a new tab)
Variant weaknessLikelihood of exploit: High
The product calls free() twice on the same memory address.
Architecture and Design
Choose a language that provides automatic memory management.
Implementation
Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly.
Implementation
Use a static analysis tool to find double free instances.

Base weaknessOWASP Top 10 A07:2025: Authentication Failures (opens in a new tab)
The product does not validate, or incorrectly validates, a certificate.
Architecture and Design · Implementation
Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
Implementation
If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.

CWE-662Improper Synchronization (opens in a new tab)
Class weakness
The product utilizes multiple threads, processes, components, or systems to allow temporary access to a shared resource that can only be exclusive to one process at a time, but it does not properly synchronize these actions, which might cause simultaneous accesses of this resource by multiple threads or processes.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Implementation
Use industry standard APIs to synchronize your code.
