Exploitation evidence

Disclosed: evidence found.
CVE published 6 Jul 2026
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 by updating to Linux kernel version 6.8.0-2049.50 or later. After applying the update, a system reboot is required to complete remediation. Due to an ABI change, third-party kernel modules must be recompiled and reinstalled. Users should follow the vendor's update instructions as provided in the Ubuntu security notice USN-8492-3.

Description

Multiple security vulnerabilities were discovered in the Linux kernel for Raspberry Pi Real-time systems affecting numerous subsystems and architectures. These issues could potentially allow an attacker to compromise the system. The vulnerabilities span a wide range of kernel components including architectures (ARM64, MIPS, PowerPC, x86), device drivers, filesystems, networking, and security modules. A patch addressing these vulnerabilities is available in version 6.8.0-2049.50.
