Insufficient validation of untrusted input in Codecs in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to perform an out of bounds memory write via a crafted video file. (Chromium security severity: Medium)
AnalysisAI
Out-of-bounds memory write in Google Chrome's codec component prior to version 149.0.7827.53 allows a remote attacker to corrupt memory by serving a crafted video file to a victim who visits a malicious page or views attacker-supplied media. The flaw stems from insufficient input validation in media codec parsing and carries a CVSS 8.8 rating reflecting high impact across confidentiality, integrity, and availability, though no public exploit identified at time of analysis and EPSS exploitation probability is very low at 0.05%.
Technical ContextAI
The vulnerability resides in Chrome's codec subsystem, which is responsible for decoding video streams within the browser's media pipeline (typically running in the renderer or a dedicated media/GPU process). The root cause is classified as CWE-20 (Improper Input Validation): the codec fails to adequately sanity-check fields in an untrusted video container or bitstream before computing buffer offsets, leading to an out-of-bounds write. Such write-primitives in media decoders are historically high-value targets because they execute on attacker-controlled bytes during routine page rendering and can be chained with a sandbox escape for full system compromise. Google rated the underlying Chromium severity as Medium, which suggests the bug is sandbox-contained absent additional escape chains.
RemediationAI
Vendor-released patch: Google Chrome 149.0.7827.53 - upgrade Stable channel browsers to this version or later via the built-in updater (chrome://settings/help) and restart the browser to apply, per the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html and the Chromium issue tracker entry at https://issues.chromium.org/issues/500028989. For managed fleets, push the update via Chrome Browser Cloud Management or your endpoint management tool and verify version compliance. Users of Chromium-based downstream browsers (Edge, Brave, Opera, Vivaldi) should update once each vendor releases a corresponding rebase. As an interim compensating control before patching, administrators can disable autoplay and restrict untrusted media playback via policy (e.g., AutoplayAllowed=false, URLBlocklist for untrusted media-heavy domains), accepting the trade-off that this breaks legitimate video on internal sites and does not prevent exploitation if a user clicks to play a malicious clip.
