Uninitialized Use in Codecs in Google Chrome on Linux, ChromeOS prior to 149.0.7827.103 allowed a remote attacker to leak cross-origin data via a crafted video file. (Chromium security severity: High)
AnalysisAI
Cross-origin data leakage in Google Chrome's codec subsystem on Linux and ChromeOS (versions prior to 149.0.7827.103) enables remote unauthenticated attackers to exfiltrate sensitive data from other origins by delivering a specially crafted video file to a target user. The root cause is uninitialized memory use (CWE-457) within the codec pipeline, where memory contents from other origin contexts may be exposed during video processing. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must be running Google Chrome on Linux or ChromeOS (Windows and macOS are not listed as affected - this is a platform-scoped vulnerability). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 4.3 (Medium) with vector AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N accurately reflects a moderate, bounded risk profile. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious web page embedding a specially crafted video file designed to trigger the uninitialized codec memory path in Chrome on Linux or ChromeOS. When a targeted user visits the page and the video begins processing, residual cross-origin memory contents are exposed to the attacker-controlled context and exfiltrated - potentially including fragments of data from other open tabs or prior codec operations. … |
| Remediation | The primary remediation is to update Google Chrome to version 149.0.7827.103 or later, as confirmed by the vendor advisory at chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
