No public nuclei template indexed

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.

What to do

Upgrade Linux kernel to 5cd2354ebfbd35bcb88d01fe7d3ee08dcf266eff or 0d6c5794fd633427f0d4ad8b51d94061295649da.

AI-suggested

An official fix has been applied to the Linux kernel to add the missing kfree() call and prevent the memory leak. Users should update to the fixed kernel version once available. No additional mitigation is required beyond applying the patch.

Description

A memory leak vulnerability in the Linux kernel's power sequencing component for pcie-m2 was fixed. The function of_regulator_bulk_get_all() allocates an array that the caller must free, but pwrseq-pcie-m2.c did not free this array, causing a memory leak. The fix adds an explicit kfree() call to release the allocated memory.
