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 6 Nov 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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 validate HID report lengths before parsing. Users should update their Linux kernel to a version that includes this fix. No additional mitigation steps are indicated.

Description

A vulnerability in the Linux kernel's asus_rog_ryujin hwmon driver allows unvalidated HID report lengths to be parsed, potentially exposing uninitialized memory bytes as sensor values via sysfs. This issue arises because the driver does not verify the presence of expected data fields before parsing them. The vulnerability has been resolved by adding validation checks for response headers and fields prior to parsing.

Impact

The vulnerability could cause the Linux kernel driver to expose uninitialized memory contents as sensor values via sysfs. While this does not directly lead to code execution or privilege escalation, it may result in information disclosure of potentially sensitive kernel memory contents.

Summary

The Linux kernel's asus_rog_ryujin hardware monitoring driver (hwmon) contained a flaw where the function rog_ryujin_raw_event() parsed HID report response headers and payload fields without verifying their presence in the received report. This lack of validation could lead to the driver consuming uninitialized bytes from the HID transport buffer and exposing these bytes as sensor values through sysfs. The fix involved validating the response header and fields used by each response type before parsing to prevent exposure of uninitialized memory.
