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 patch is available and should be applied to affected Linux kernel versions to address this issue. The fix ensures proper checking of runtime resume results and correct cleanup of power management references during the probe process.

Description

A vulnerability in the Linux kernel's ASoC Mediatek mt8192 driver was resolved. The issue involves improper handling of runtime power management during the probe process, where failures in runtime resume are not properly checked, potentially leading to incorrect power management usage counts and device accessibility issues. The flaw was fixed by improving the runtime resume checks and ensuring proper cleanup of power management references.

Impact

If runtime resume fails during the probe, the device may be considered accessible when it is not, and the power management usage count may be left incremented, potentially causing power management inconsistencies. This could affect device stability and power management behavior but does not directly indicate remote code execution or privilege escalation.

Summary

The Linux kernel's ASoC Mediatek mt8192 audio front-end (AFE) probe temporarily enables runtime power management (PM) while reinitializing the regmap cache from hardware. However, it uses pm_runtime_get_sync() without verifying the return value. If runtime resume fails, the probe continues without confirming device accessibility, and the PM usage count may be incremented incorrectly. Additionally, failure paths in regmap_reinit_cache() return before dropping the temporary PM reference and clearing the pm_runtime_bypass_reg_ctl flag. The fix replaces pm_runtime_get_sync() with pm_runtime_resume_and_get() to prevent usage count leaks on resume failure and ensures the bypass flag is cleared after dropping the PM reference in all failure cases.
