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 release the clock reference after reading the rate in read_dts_node(), including error paths. Users should update to the fixed kernel version when available. Patch status is not explicitly confirmed in the provided data; check the vendor advisory for current remediation guidance.

Description

A vulnerability in the Linux kernel's fsl/fman component involved a clock reference leak in the read_dts_node() function. The function of_clk_get() increments the clock's reference count but read_dts_node() reads the clock rate without releasing the reference, causing a leak. This issue has been resolved by ensuring the clock reference is released after reading the rate, including error paths.
