CVE-2026-58965

Summary

A confused deputy vulnerability in handleAudioEffectBroadcast allows an unprivileged local process to bypass permission checks and gain full local privilege escalation (confidentiality, integrity, availability) without user interaction.

Exploitability

Exploitation is straightforward for a local attacker with no additional privileges or user interaction required, leveraging the confused deputy pattern to abuse internal broadcast handling.

Blast radius

Successful exploitation grants full control over the affected service or device, enabling data theft, system modification, or denial of service by any local unprivileged process.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Apply the vendor patch for CVE-2026-58965 when released; until then, restrict access to the handleAudioEffectBroadcast endpoint by enforcing strict permission checks in MusicFxHelper.java and disabling non-essential audio effect broadcasting features.
