HIGH 8.8

DescriptionCVE.org

Integer overflow in Media in Google Chrome prior to 147.0.7727.55 allowed a remote attacker to potentially exploit heap corruption via a crafted video file. (Chromium security severity: Low)

AnalysisAI

Integer overflow in Google Chrome's media handling (versions prior to 147.0.7727.55) enables remote attackers to trigger heap corruption through specially crafted video files, achieving potential arbitrary code execution with high confidentiality, integrity, and availability impact. Attack requires user interaction to open malicious media content. Exploitation is unauthenticated (network-accessible). No public exploit identified at time of analysis. Classified as low severity by Chromium project despite CVSS 8.8 rating.

Technical ContextAI

CWE-472 integer overflow in Chrome's media processing pipeline causes heap corruption when parsing video file metadata or frame data. Overflow condition bypasses bounds checks during buffer allocation, enabling attacker-controlled memory corruption. CPE cpe:2.3:a:google:chrome applies to all platforms prior to patched release.

RemediationAI

Vendor-released patch: Google Chrome version 147.0.7727.55 resolves this vulnerability. Users must upgrade immediately via built-in Chrome update mechanism (Settings > About Chrome) or download from official channels. Enterprise deployments should push updates through managed update infrastructure. No workarounds exist; mitigation requires patching. Upstream fix tracked at Chromium issue 485212874. Official advisory available at https://chromereleases.googleblog.com/2026/04/stable-channel-update-for-desktop.html. Organizations unable to patch immediately should implement network-layer restrictions on untrusted video file sources and enforce browser security policies prohibiting automatic media playback.
