DescriptionNVD

Insufficient validation of untrusted input in CameraCapture in Google Chrome on ChromeOS prior to 150.0.7871.47 allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page. (Chromium security severity: Low)

AnalysisAI

Out-of-bounds memory read in the CameraCapture component of Google Chrome on ChromeOS (versions prior to 150.0.7871.47) lets a remote attacker leak adjacent process memory when a victim opens a crafted HTML page. No public exploit identified at time of analysis, and EPSS is low (0.17%), but the flaw is marked automatable by CISA SSVC. Note a signal conflict: the NVD CVSS is 8.1 (high) while Google rates the Chromium security severity as Low.

Technical ContextAI

The defect is a CWE-125 (Out-of-Bounds Read) in Chrome's CameraCapture code path, which handles camera/media stream capture on ChromeOS. Insufficient validation of untrusted input (attacker-controlled data reaching the capture routine via a web page) causes a read beyond the bounds of an allocated buffer, exposing data from adjacent heap or process memory. The affected software is Google Chrome (CPE cpe:2.3:a:google:chrome), specifically the ChromeOS build; the browser's multi-process/sandbox architecture typically constrains such reads to the renderer or a media-related process rather than the OS kernel.

RemediationAI

Vendor-released patch: 150.0.7871.47 - update Google Chrome / ChromeOS to 150.0.7871.47 or later via the Stable channel, per the Chrome Releases advisory (https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html). Chrome and ChromeOS normally auto-update, so the practical step is to ensure managed devices are not pinned to an older channel/version and to force a relaunch to apply the update. As an interim compensating control, restrict or block camera/media-capture permissions for untrusted sites via enterprise policy (e.g., set VideoCaptureAllowed / site permission defaults to deny), accepting the trade-off that legitimate camera-based web apps will stop working; this narrows exposure to the CameraCapture path until devices are updated.
