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 driver to free allocated memory and revert hardware state on error. Users should update to the fixed kernel version containing this patch. No additional mitigation steps are indicated.

Description

A vulnerability in the Linux kernel driver for the Kionix KX022A accelerometer (iio: accel: kionix-kx022a) has been resolved. The issue involved a memory leak when regmap operations failed during the buffer enable path, causing allocated memory not to be freed. Additionally, hardware state and configuration were not properly reverted on error, potentially leaving interrupts and buffers enabled incorrectly. The fix ensures memory is freed and hardware state is restored on error.
