Exploitation evidence

Disclosed: evidence found.
CVE published 24 Sep 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 users should update to linux-realtime kernel version 6.8.1-1034.35 or later. After updating, a system reboot is required to apply the changes. Due to an ABI change, all third-party kernel modules must be recompiled and reinstalled. Follow the official Ubuntu security notice USN-7767-1 for detailed update instructions.

Description

Multiple security vulnerabilities were discovered in the Linux kernel real-time (linux-realtime) variant affecting numerous subsystems and architectures. These flaws could potentially allow an attacker to compromise the system. The issues impact a wide range of components including ARM and x86 architectures, various device drivers, networking stacks, memory management, and more. A patch addressing these vulnerabilities is available in linux-realtime kernel version 6.8.1-1034.35. Users are advised to update and reboot to apply the fixes. Due to ABI changes, recompilation of third-party kernel modules may be required.

Impact

An attacker could potentially exploit these vulnerabilities to compromise the affected system. The broad range of affected subsystems indicates multiple attack vectors, potentially impacting system stability, security, and confidentiality. However, no known exploits in the wild have been reported at this time.

Summary

The linux-realtime kernel contains multiple security flaws across many subsystems such as ARM32, ARM64, x86 architectures, device drivers (GPU, network, USB, etc.), networking protocols (IPv4, IPv6, VLAN, Netfilter), memory management, scheduler infrastructure, and others. These vulnerabilities collectively could allow attackers to compromise system integrity or availability. The issues are tracked under CVE-2024-58090 and a large set of related CVEs. Ubuntu has released an official security update (USN-7767-1) fixing these issues in version 6.8.1-1034.35 of the linux-realtime kernel. The update requires a system reboot and recompilation of third-party kernel modules due to ABI changes.
