Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB

No attack traffic recorded by OffSeq Mirage sensors

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.

What to do

Upgrade Linux kernel to 8042312e73c50de82634ce63eae7cf219464b481, 995f22b2881835b518b3f99240d00781c9df0235 or 1caa5f9399ff107a8fa221b1eaca0a9e729d3758.

Description

In the Linux kernel, the following vulnerability has been resolved: hwmon: (asus_rog_ryujin) Validate HID report lengths rog_ryujin_raw_event() parses response headers and payload fields without first checking that they are present in the received report. A short report can therefore make the driver consume uninitialized bytes from the HID transport buffer and expose them as sensor values through sysfs. Validate the response header and the fields used by each response type before parsing them.
