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.

AI-suggested

A patch is available and should be applied immediately by updating to the fixed kernel versions 5.15.0-1084.87, 5.15.0-1085.91, or 5.15.0-1088.94 depending on the platform. After updating, a system reboot is required to apply the changes. Due to ABI changes, all third-party kernel modules must be recompiled and reinstalled. Follow the vendor advisory at https://ubuntu.com/security/notices/USN-7704-3 for detailed update instructions.

Description

Multiple security vulnerabilities were discovered in the Linux kernel affecting various subsystems including cryptographic APIs, device drivers, media, networking, file systems, and others. These flaws could potentially allow an attacker to compromise the system. The issues are addressed in updated Linux kernel packages for several platforms including IBM cloud systems, Intel IoT platforms, Oracle Cloud systems, and Raspberry Pi systems. Users must update to fixed versions and reboot to apply the patches. Due to ABI changes, recompilation of third-party kernel modules is required after updating.

Impact

An attacker could potentially exploit these vulnerabilities to compromise the affected Linux systems. The flaws span critical kernel subsystems including cryptography, device drivers, networking, and file systems, which could lead to privilege escalation, denial of service, or other system compromises if exploited.

Summary

CVE-2025-38003 is part of a set of security issues discovered in the Linux kernel impacting multiple subsystems such as Cryptographic API, Arm Firmware Framework for ARMv8-A, various device drivers, media and network drivers, file systems infrastructure, SMB network file system, and others. These vulnerabilities could be exploited by attackers to compromise affected systems. The issues affect multiple Linux kernel variants including linux-ibm, linux-intel-iotg, linux-oracle, and linux-raspi. Fixed versions have been released (5.15.0-1084.87, 5.15.0-1085.91, 5.15.0-1088.94). The vendor advisory from Ubuntu (USN-7704-3) provides detailed update instructions and notes the necessity to reboot and recompile third-party kernel modules due to ABI changes.
