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.

Description

In the Linux kernel, the following vulnerability has been resolved: misc: ad525x_dpot: use driver core groups for sysfs files ad_dpot_probe() creates per-RDAC sysfs files manually and then optionally creates the command sysfs group. This leaves probe responsible for rolling back partial sysfs state and makes remove responsible for matching every file that probe created. Move the device attributes into driver core dev_groups for the I2C and SPI drivers and use an is_visible() callback to expose only the attributes supported by the probed device. With this shape, the driver core creates the sysfs files only after probe succeeds and removes them before the remove callback frees the driver data.
