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

An official fix is available that reorders power management runtime enablement and device registration calls in the imx mailbox driver. Users should apply the updated Linux kernel version containing this fix. No additional manual mitigation is indicated.

Description

A vulnerability in the Linux kernel's imx mailbox driver was resolved by adjusting the power management runtime enablement sequence. The issue involved early usage of the device before probe completion, which could lead to improper device removal and shutdown handling. The fix delays pm_runtime_enable() to the removal path and reorders device registration to ensure proper cleanup.
