CVE-2026-17729 is a use-after-free vulnerability (CWE-416) in the V8 engine of Google Chrome before version 151.0.7922.72. It allows a remote attacker with control over the renderer process to potentially execute out-of-bounds memory access via crafted HTML content. The vulnerability could lead to memory corruption issues but requires prior compromise of the renderer process. The Chromium project rates this vulnerability as medium severity. No CVSS score or vendor advisory patch information is provided in the available data.

An attacker who has already compromised the renderer process in affected versions of Google Chrome could exploit this vulnerability to perform out-of-bounds memory access. This may lead to memory corruption, potentially enabling further exploitation or denial of service. However, exploitation requires prior renderer compromise, limiting the initial attack vector. No known active exploits have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should update Google Chrome to version 151.0.7922.72 or later once available. Until then, no specific mitigations are provided in the input data.
