Exploitation evidence

Disclosed: evidence found.
CVE published 3 Sep 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 2026-10-25.

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.

AI-suggested

Red Hat has released updated kpatch live patch modules (kpatch-patch-5_14_0-427_13_1 and kpatch-patch-5_14_0-427_31_1) that address these vulnerabilities. Users should apply the provided updates according to Red Hat's guidance in advisory RHSA-2024:6242 and reboot the system to activate the patches. This is the official fix for these issues.

Description

Red Hat has released a security advisory for a kernel live patch module targeting kernel-5.14.0-427.13.1.el9_4. The update addresses two denial of service vulnerabilities (CVE-2024-41090 and CVE-2024-41091) related to the virtio-net tap and tun drivers interacting with mlx5_core. These vulnerabilities could allow denial of service via short frame handling. The advisory rates the impact as Important and requires a system reboot after applying the update. The update is available for various Red Hat Enterprise Linux 9 variants on x86_64 and ppc64le architectures.

Impact

Successful exploitation of these vulnerabilities could result in denial of service conditions affecting the network interfaces using virtio-net tap and tun with mlx5_core. This could disrupt network connectivity or degrade system availability. No known exploits in the wild have been reported at the time of this advisory.

Summary

This advisory covers security fixes in kpatch live patch modules for Red Hat Enterprise Linux 9 kernels version 5.14.0-427.13.1.el9_4. The vulnerabilities CVE-2024-41090 and CVE-2024-41091 relate to denial of service conditions caused by short frames in the virtio-net tap and tun interfaces interacting with mlx5_core. The kpatch modules allow live patching of the running kernel to mitigate these issues without full kernel replacement. The vendor rates the update as Important and requires a reboot to apply the patches. The advisory references Red Hat's errata RHSA-2024:6242 for detailed instructions and affected product lists.

CWE-20Improper Input Validation (opens in a new tab)
Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #18OWASP Top 10 A05:2025: Injection (opens in a new tab)
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Attack Surface Reduction
Consider using language-theoretic security (LangSec) techniques that characterize inputs using a formal language and build "recognizers" for that language. This effectively requires parsing to be a distinct layer that effectively enforces a boundary between raw input and internal data representations, instead of…
Architecture and Design · Libraries or Frameworks
Use an input validation framework such as Struts or the OWASP ESAPI Validation API. Note that using a framework does not automatically address all input validation problems; be mindful of weaknesses that could arise from misusing the framework itself (CWE-1173).
Architecture and Design · Implementation · Attack Surface Reduction
Understand all the potential areas where untrusted inputs can enter the product, including but not limited to: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any…
