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 and merged into the Linux kernel. Users should update to the fixed kernel version 6.5 or later containing the referenced commits to resolve the issue. No additional mitigation steps are required beyond applying the official patch.

Description

A vulnerability in the Linux kernel's tps6594 regulator driver caused device node reference leaks in a multiphase loop. The flaw involved missing release calls for device node references acquired during the loop, leading to resource leaks. Additionally, a missing NULL check after a node lookup could cause a NULL pointer dereference. The issue has been fixed by adding proper NULL checks and ensuring all node references are released at each loop iteration.

Impact

The vulnerability could lead to resource leaks in the kernel due to unreleased device node references, potentially degrading system stability or causing memory exhaustion over time. The NULL pointer dereference risk could cause kernel crashes or denial of service if triggered. There is no indication of remote code execution or privilege escalation. No known exploits in the wild have been reported.
