Exploitation evidence

Disclosed: evidence found.
CVE published 2 Oct 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 6.8.0-1036.42~22.04.1 (linux-azure-6.8 package) or 6.8.0-1038.44 (linux-azure package).

AI-suggested

A patch is available and should be applied promptly. The vendor advisory (Ubuntu USN-7802-1) provides updated package versions for Ubuntu 22.04 LTS and 24.04 LTS linux-azure kernels. After updating, a system reboot is required to apply the fixes. Note that due to an ABI change, third-party kernel modules must be recompiled and reinstalled. Users should update to linux-image-6.8.0-1036.42~22.04.1 or linux-image-6.8.0-1038.44 as appropriate for their Ubuntu release.

Description

Multiple security vulnerabilities were discovered and fixed in the Linux kernel for Azure cloud systems, affecting numerous subsystems including architectures (ARM32, ARM64, x86), various device drivers, networking components, filesystems, memory management, and more. These flaws could potentially allow an attacker to compromise the system. Updates correcting these issues have been released for Ubuntu 22.04 LTS and 24.04 LTS Linux-azure kernels.

Impact

The vulnerabilities collectively could allow attackers to compromise the affected systems running vulnerable Linux-azure kernels. The broad range of affected subsystems suggests potential for privilege escalation, denial of service, or other impacts depending on the specific flaw. However, no specific exploitation in the wild is reported. The impact is significant given the kernel-level nature of the flaws and the wide scope of affected components.

Summary

This advisory addresses a broad set of security issues in the Linux kernel specifically for the linux-azure and linux-azure-6.8 packages. The vulnerabilities impact a wide range of kernel subsystems such as ARM and x86 architectures, device drivers (GPU, network, USB, etc.), filesystems (NFS, SMB, Overlay), networking protocols (IPv4, IPv6, VLAN, Netfilter), memory management, scheduler infrastructure, and others. The update fixes these flaws in the specified kernel versions. The vendor advisory confirms that these issues could allow an attacker to compromise the system if unpatched. The affected versions include multiple 6.8 kernel builds and some 6.5 and 6.6 versions, with fixes available in 6.8.0-1036.42~22.04.1 and 6.8.0-1038.44.
