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 26 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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 fix has been implemented in the Linux kernel to reject out-of-range OCF values instead of aliasing them onto unrelated commands. Users and administrators should apply the official Linux kernel update that includes this patch to mitigate the vulnerability. No additional mitigation steps are indicated.

Description

A vulnerability in the Linux kernel's Bluetooth raw HCI socket security filter allows unprivileged sockets to submit out-of-range OCF values that alias allowlisted commands. This occurs because the filter masks the 10-bit OCF with 127, causing reserved OCF values to be treated as valid commands. The issue has been resolved by rejecting OCF values that cannot be represented by the security filter instead of aliasing them.
