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 is available and has been applied in the Linux kernel by replacing debugfs_create_file_unsafe() with debugfs_create_file() for the affected debugfs file operations. Users should update to the fixed kernel version once available.

Description

A vulnerability in the Linux kernel's iio: imu: adis16480 driver involved unprotected debugfs reads. The firmware_revision and firmware_date file operations did not properly use debugfs_file_get(), causing debugfs_remove_recursive() to not wait for ongoing reads. This could lead to the iio_dev device being freed while still in use. The issue was fixed by replacing debugfs_create_file_unsafe() with debugfs_create_file().
