Exploitation evidence

Disclosed: evidence found.
CVE published 12 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.

What to do

AI-suggested

Red Hat has released updated kpatch live patch modules to address these vulnerabilities. Users should apply the kpatch-patch-4_18_0-305_120_1 and kpatch-patch-4_18_0-305_138_1 updates for Red Hat Enterprise Linux 8.4 Update Services for SAP Solutions. After applying the update, a system reboot is required for the patch to take effect. Refer to Red Hat's official update guide at https://access.redhat.com/articles/11258 for detailed instructions.

Description

This advisory addresses two denial of service vulnerabilities (CVE-2024-41090 and CVE-2024-41091) in the Red Hat Enterprise Linux kernel live patch modules for kernel version 4.18.0-305.120.1.el8_4. The vulnerabilities involve the virtio-net tap and tun drivers interacting with mlx5_core, which can cause short frame denial of service conditions. Red Hat has released updated kpatch modules to fix these issues. Systems must be rebooted after applying the update for the patch to take effect.

Impact

The vulnerabilities can cause denial of service conditions in the kernel's virtio-net tap and tun drivers when used with mlx5_core. This could disrupt network functionality on affected systems running the specified kernel version. No known exploits in the wild have been reported. The impact is limited to denial of service and does not indicate privilege escalation or code execution.

Summary

Red Hat issued a security advisory for kpatch live patch modules targeting kernel-4.18.0-305.120.1.el8_4 to address two denial of service vulnerabilities identified as CVE-2024-41090 and CVE-2024-41091. These vulnerabilities affect the virtio-net tap and tun drivers in conjunction with mlx5_core, potentially allowing short frame denial of service attacks. The advisory provides updated kpatch modules (kpatch-patch-4_18_0-305_120_1 and kpatch-patch-4_18_0-305_138_1) as fixes. The update requires a system reboot to activate the patch. The vulnerabilities are rated with an important security impact by Red Hat, and no CVSS score is provided in the advisory.

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).
