Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB

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 30 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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.

AI-suggested

A patch is available and users should update their Linux kernel packages to the fixed versions listed in the Ubuntu advisory USN-7725-3. After updating, a system reboot is required to apply the changes. Due to an ABI change, any third-party kernel modules must be recompiled and reinstalled. Standard system upgrades will typically handle this automatically unless kernel metapackages have been manually removed.

Description

Multiple security vulnerabilities were discovered in the Linux kernel affecting subsystems such as the Overlay file system and Network traffic control. These flaws could potentially allow an attacker to compromise the system. The issues have been addressed in updated Linux kernel packages for various Ubuntu releases including 22.04 LTS and 24.04 LTS. Users are advised to apply the updates and reboot their systems to ensure the fixes are applied. Due to an ABI change, recompilation and reinstallation of third-party kernel modules may be required.

Impact

If exploited, these vulnerabilities could allow an attacker to compromise the affected Linux system, potentially leading to unauthorized access or control. The exact nature of the compromise is not detailed, but the affected subsystems suggest possible impacts on file system integrity and network traffic control. No known exploits in the wild have been reported at this time.

Summary

Several security issues were identified in the Linux kernel, specifically impacting the Overlay file system and Network traffic control subsystems. These vulnerabilities could be exploited by attackers to compromise affected systems. The issues are tracked under CVE identifiers including CVE-2024-57996, CVE-2025-21887, CVE-2025-38350, and CVE-2025-37752. Canonical has released patched kernel versions for Ubuntu 22.04 LTS and 24.04 LTS variants such as linux-gcp-6.8, linux-gke, linux-nvidia, and others. The updates require a system reboot and recompilation of third-party kernel modules due to ABI changes. The vendor advisory is detailed in Ubuntu Security Notice USN-7725-3.
