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 to properly validate the firmware data length and prevent out-of-bounds reads. Users should update to the fixed kernel version once available. No additional mitigation steps are indicated.

Description

A vulnerability in the Linux kernel's iio proximity driver for aw96103 was resolved by improving validation of firmware data length. The firmware parser previously could read beyond the buffer or interpret an underflowed length as a very large value, potentially causing out-of-bounds reads. The fix involves validating header size, rejecting underflowed lengths, and ensuring the payload fits within the firmware image.
