Exploitation evidence

Disclosed: evidence found.
CVE published 25 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.

What to do

Upgrade the Ubuntu to 6.8.0-1037.37~22.04.1 (linux-ibm-6.8 package) or 6.8.0-1037.37 (linux-ibm package).

AI-suggested

Apply the official security updates provided by Ubuntu for linux-ibm-6.8 kernel packages to versions 6.8.0-1037.37 and 6.8.0-1037.37~22.04.1 or later. After updating, reboot the system to activate the fixes. Due to ABI changes, recompile and reinstall all third-party kernel modules. Follow the update instructions in the Ubuntu security notice USN-7779-1 at https://ubuntu.com/security/notices/USN-7779-1.

Description

Multiple security vulnerabilities were discovered in the Linux kernel affecting a wide range of subsystems and architectures including ARM32, ARM64, x86, various device drivers, networking components, and file systems. These flaws could potentially allow an attacker to compromise the affected system. Updates correcting these issues have been released for the linux-ibm-6.8 kernel packages. Users should apply the updates and reboot to ensure the fixes take effect.

Impact

An attacker could potentially exploit these vulnerabilities to compromise the system running the affected Linux kernel versions. The broad range of affected subsystems indicates multiple attack vectors, but specific exploitation details or confirmed in-the-wild exploitation are not reported.

Summary

The Linux kernel for IBM cloud systems (linux-ibm-6.8) contains numerous security vulnerabilities across many subsystems such as ARM32/ARM64/x86 architectures, device drivers (GPU, network, USB, etc.), file systems (NFS, SMB, Overlay), networking protocols (IPv4, IPv6, VLAN, Netfilter), and kernel infrastructure components (memory management, scheduler, tracing). These vulnerabilities could be exploited by attackers to compromise system security. The issues are addressed in updated kernel versions 6.8.0-1037.37 and 6.8.0-1037.37~22.04.1. The update requires a system reboot and recompilation of third-party kernel modules due to ABI changes.
