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 source by adding proper range checks in the driver code. Users should update their Linux kernel to a version that includes this fix once it is released. Patch status is not explicitly confirmed in the provided data; therefore, users should consult the official Linux kernel advisories or source repositories for the fixed version.

Description

A vulnerability in the Linux kernel's chips-media wave5 driver was fixed by adding range checks to the dec_output_info structure. Without these checks, invalid data could cause the driver to write to invalid memory, leading to a buffer overflow condition. This issue was identified by a static analysis tool (smatch) and corrected to prevent potential memory corruption.

Impact

If exploited, this vulnerability could cause the driver to write to invalid memory locations, potentially leading to system instability or crashes. However, no known exploits are reported in the wild. The impact is limited to systems using the affected chips-media wave5 driver in the Linux kernel.

Summary

The Linux kernel's chips-media wave5 driver had a vulnerability where the dec_output_info structure could contain invalid data, allowing the driver to write outside valid memory bounds. Specifically, a buffer overflow was detected in the wave5_vpu_dec_get_output_info() function related to the frame_buf buffer size check. The fix involved adding range checks to ensure that the dec_output_info data is valid before use, preventing invalid memory writes.
