Exploitation evidence

Disclosed: evidence found.
CVE published 8 Jul 2025
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
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 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 should be applied by updating to linux-oem-6.11 version 6.11.0-1025.25 or later. After updating, a system reboot is required to activate the fixes. Due to an ABI change, all third-party kernel modules must be recompiled and reinstalled. Users should follow the official Ubuntu security notice USN-7610-2 for detailed update instructions.

Description

Multiple security vulnerabilities were identified in the Linux kernel subsystems Netfilter and Network traffic control. These flaws could potentially allow an attacker to compromise affected systems. The issues affect various versions of the linux-oem-6.11 kernel and have been addressed in an updated kernel release. Users are advised to apply the update and reboot to ensure the fixes take effect.

Impact

If exploited, these vulnerabilities could allow an attacker to compromise the affected Linux systems, potentially leading to unauthorized access or control. The exact nature of the compromise is not detailed, but the affected subsystems suggest possible network-related attack vectors.

Summary

Several security issues were discovered in the Linux kernel, specifically within the Netfilter and Network traffic control subsystems. These vulnerabilities, including CVE-2025-37798 among others, could be exploited by attackers to compromise the system. The affected linux-oem-6.11 kernel versions include multiple specific builds prior to 6.11.0-1025.25. A patch fixing these issues is available in version 6.11.0-1025.25. The update requires a system reboot and recompilation of third-party kernel modules due to an ABI change.
