Exploitation evidence

Disclosed: evidence found.
CVE published 8 Jun 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 3 Nov 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 5.15.0-1090.97+fips1 (linux-aws-fips package) or 5.15.0-152.162+fips1 (linux-fips package) or 5.15.0-1090.99+fips1 (linux-gcp-fips package).

AI-suggested

Apply the official security updates provided by Ubuntu as detailed in USN-7704-2. After updating, reboot the system to ensure all changes take effect. Due to ABI changes in the kernel, recompile and reinstall any third-party kernel modules. The fixed versions are 5.15.0-1090.97+fips1, 5.15.0-152.162+fips1, and 5.15.0-1090.99+fips1. No additional mitigation is required beyond applying these updates.

Description

Multiple security vulnerabilities were discovered in the Linux kernel affecting various subsystems including cryptographic APIs, device drivers, media, networking, and file systems. These flaws could potentially allow an attacker to compromise the system. The issues have been addressed in updated Linux kernel packages for FIPS-certified versions on AWS, GCP, and generic Linux distributions. Users are advised to apply the updates and reboot to ensure all fixes are applied.

Impact

An attacker could potentially exploit these vulnerabilities to compromise the affected Linux systems. The vulnerabilities span critical kernel subsystems including cryptography and networking, which could lead to unauthorized access or system instability if exploited. However, there are no known exploits in the wild at this time.

Summary

CVE-2025-38003 is part of a set of security issues found in the Linux kernel impacting numerous subsystems such as the Cryptographic API, ARM firmware framework, multiple device drivers, media and network drivers, NVDIMM and NVME drivers, x86 platform drivers, file system infrastructure, SMB network file system, LZO compression library, digital audio drivers, tracing infrastructure, and others. These vulnerabilities could be exploited by attackers to compromise affected systems. The issues have been fixed in Linux kernel versions 5.15.0-1090.97+fips1, 5.15.0-152.162+fips1, and 5.15.0-1090.99+fips1. The fixes are available through Ubuntu security notices and require a system reboot and recompilation of third-party kernel modules due to ABI changes.
