AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Remote crafted page with low complexity and no auth, but requires the victim to open it (UI:R); in-renderer code execution keeps scope unchanged with high C/I/A.

Use after free in Codecs in Google Chrome prior to 147.0.7727.138 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Remote code execution in Google Chrome desktop before 147.0.7727.138 stems from a use-after-free in the browser's Codecs component, letting a remote attacker who lures a victim to a crafted HTML page corrupt memory and run arbitrary code within Chrome's renderer sandbox. Rated High severity by Chromium with CVSS 8.8, it requires user interaction (visiting a malicious page) but no authentication. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; EPSS is very low at 0.01%.
Technical ContextAI
The flaw is a CWE-416 use-after-free in Chrome's media Codecs subsystem, the code responsible for decoding audio/video streams embedded in web content. A use-after-free occurs when a pointer to freed heap memory is reused, allowing an attacker who controls heap layout to place attacker-controlled data where a stale object is expected, corrupting object state or vtables to hijack control flow. Because codec parsing runs on richly attacker-influenced input (media containers/streams referenced from an HTML page), it is a classic memory-corruption attack surface. The affected CPE is cpe:2.3:a:google:chrome, i.e. the Chrome browser application across pre-147.0.7727.138 builds; the arbitrary code execution is explicitly noted as occurring inside the renderer sandbox, so a further sandbox-escape would be needed for full host compromise.
RemediationAI
Vendor-released patch: update Google Chrome to 147.0.7727.138 or later on all desktop platforms (Windows, macOS, Linux) via the built-in updater or by relaunching the browser, per https://chromereleases.googleblog.com/2026/04/stable-channel-update-for-desktop_28.html. For Chromium-based and vendor-repackaged builds, apply the equivalent update from Red Hat/SUSE or the respective vendor as it ships. Where immediate patching is not possible, reduce exposure by restricting untrusted browsing, deploying enterprise policy to force-update Chrome, and considering a stricter site-isolation posture; disabling the sandbox is not a mitigation and would worsen risk. As a codec-focused UAF, temporarily limiting exposure to untrusted media-heavy sites lowers likelihood but does not eliminate the flaw, so treat it only as a stopgap until the update is applied.
