Use after free in Web MIDI in Google Chrome on Android prior to 146.0.7680.178 allowed a remote attacker to execute arbitrary code via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Remote code execution in Google Chrome on Android via use-after-free vulnerability in Web MIDI allows unauthenticated remote attackers to execute arbitrary code through a crafted HTML page. The vulnerability affects Chrome versions prior to 146.0.7680.178 and carries high severity per Chromium's security classification. A vendor-released patch is available.
Technical ContextAI
The vulnerability is a use-after-free (CWE-416) memory corruption flaw in the Web MIDI API implementation within Google Chrome's Android rendering engine. Web MIDI (Web Audio API MIDI support) enables JavaScript access to MIDI input/output devices via the browser. The use-after-free occurs when memory previously allocated to a MIDI-related object is freed but subsequently accessed without proper validation, allowing an attacker to manipulate freed memory and potentially redirect execution flow. This is a memory safety vulnerability endemic to C++-based browser engines when object lifecycle management fails. The defect is specific to Android, suggesting platform-specific MIDI handling code paths contain the flaw.
RemediationAI
Users must upgrade Google Chrome on Android to version 146.0.7680.178 or later, which contains the vendor-released patch. This update is available through the Google Play Store automatic update mechanism or manual installation via Settings > Apps > Chrome > Update. For enterprise deployments, administrators should enforce policy-driven updates via Chrome Enterprise management console. No configuration workarounds or version-specific mitigations are documented; patching is the sole remediation path. Verification of installed version can be confirmed via Chrome Settings > About Chrome, which displays the current version and initiates automatic update checks.
