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 applied to the Linux kernel to return the cached error value when a read fails in the rohm-bm1390 driver. Users should update to a kernel version that includes this fix. Patch status is not explicitly confirmed in the provided data; users should consult the vendor or kernel release notes for the specific patch version and apply the update accordingly.

Description

A vulnerability in the Linux kernel's iio pressure driver for rohm-bm1390 sensors caused the data reading function to ignore cached error values and always return 0, even when a read operation failed. This could lead to user-space applications receiving invalid data without indication of failure. The issue has been resolved by modifying the function to return the cached error value after stopping the measurement, ensuring that users are informed if a read fails and that invalid data is not silently propagated.

Impact

User-space applications relying on the rohm-bm1390 sensor data could receive invalid data without any error indication, potentially leading to incorrect behavior or decisions based on corrupted sensor readings. There is no indication of further impact such as privilege escalation or denial of service.

Summary

The Linux kernel's iio pressure driver for rohm-bm1390 sensors had a flaw where the data reading function ignored cached error values and unconditionally returned 0. This meant that if a read operation failed, the function would not report the error, causing user-space to potentially process garbage data. The fix involves returning the cached error value after stopping the measurement, allowing the user to detect read failures.
