Use after free in Ozone in Google Chrome on Linux prior to 149.0.7827.103 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Heap corruption in Google Chrome's Ozone component on Linux before version 149.0.7827.103 allows remote attackers to potentially achieve arbitrary code execution within the browser process when a victim visits a crafted HTML page. The flaw is a use-after-free rated High severity by Chromium, with CVSS 8.8 reflecting network-reachable exploitation requiring only minimal user interaction. No public exploit identified at time of analysis, and the vulnerability is not currently listed in CISA KEV.
Technical ContextAI
Ozone is Chromium's platform abstraction layer for low-level windowing, input, and graphics on Linux (and Chrome OS), bridging the browser to backends such as X11 and Wayland. The vulnerability is a CWE-416 Use-After-Free, where an object is freed while a reference to it remains live, allowing later access to reclaimed memory and enabling heap corruption. In a renderer or browser-side Ozone path, such corruption can be steered into a controlled write or type-confusion primitive, which historically maps to sandboxed code execution in Chrome and forms the first stage of a multi-bug exploit chain.
RemediationAI
Vendor-released patch: Google Chrome 149.0.7827.103 for Linux; update affected endpoints to this version or later via the standard stable channel update described at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html. For managed fleets, push the update through your Chrome enterprise policy or package manager and verify chrome://version reports 149.0.7827.103+; restart all browser processes since Chrome does not apply binary updates until relaunch. Users of Chromium-derived browsers should monitor their respective vendors for backported builds and update once available. As an interim compensating control before patching, restrict browsing on Linux workstations to trusted sites (URL allowlists via enterprise policy) and ensure site isolation is enabled (default) so that a crafted page is confined to a per-site renderer - this does not block the bug but raises the cost of a useful exploit chain; disabling JavaScript would reduce reachability but is generally too disruptive for production use.
