Exploitation evidence

Disclosed: evidence found.
CVE published 8 May 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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 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 the Red Hat redhat/libvirt package to 9.9, 9.7 or 9.5.

AI-suggested

A security update is available from Red Hat for libvirt packages on Red Hat Enterprise Linux 9. Users should apply the official patches as described in the Red Hat advisory RHSA-2024:4757. Refer to https://access.redhat.com/articles/11258 for update instructions. No additional mitigation steps are indicated by the vendor.

Description

A security update addresses a stack use-after-free vulnerability in the libvirt component of Kernel-based Virtual Machine (KVM) virtualization on Linux. The flaw, identified as CVE-2024-4418, occurs in the virNetClientIOEventLoop() function and could potentially lead to memory corruption. This vulnerability affects Red Hat Enterprise Linux 9 and related packages. A patch is available from Red Hat to remediate the issue.

Impact

The vulnerability could allow an attacker to cause memory corruption via a use-after-free condition in libvirt's network client event loop. This may lead to unexpected behavior or potential denial of service in virtual machine management environments. No known exploits are reported in the wild at this time.

Summary

CVE-2024-4418 is a stack use-after-free vulnerability in the virNetClientIOEventLoop() function of libvirt, a user-space component used to manage virtual machines running on KVM virtualization on Linux. This vulnerability could lead to memory corruption issues. The Red Hat Product Security Team has issued a security advisory and released updated libvirt packages for Red Hat Enterprise Linux 9 to fix this issue. The vulnerability is rated as moderate severity by Red Hat. No CVSS score is provided in the advisory.
