CVE-2026-15777

chromium-browser: chromium-browser: Use after free in UI

Published Jul 14, 2026 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed

Description

Use after free in UI in Google Chrome on Linux prior to 150.0.7871.125 allowed a remote attacker who convinced a user to engage in specific UI gestures to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

Analysis

Technical impact

A use‑after‑free flaw in Google Chrome’s Linux user interface can be triggered by a malicious web page that forces a user to perform specific gestures. The bug allows an attacker to corrupt the browser’s heap and potentially redirect control flow, which can lead to arbitrary code execution. The weakness is identified as CWE‑416 and CWE‑825.

Affected Systems

Google Chrome installations on Linux that are earlier than version 150.0.7871.125 are affected. Any user running a desktop build of Chrome from the stable channel before that release is at risk.

Risk and Exploitability

The CVSS base score of 7.5 indicates high severity, yet the EPSS score of less than 1 % suggests that known exploits are rare. The vulnerability is not listed in the CISA KEV catalog. Exploitation requires a user to visit a specially crafted HTML page and perform predetermined UI actions, making it a user‑initiated attack that still demands successful heap corruption for code execution.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
