v8 memory safety

The v8 memory safety tag covers vulnerabilities in Google's V8 JavaScript engine that affect Chromium-based browsers on Windows. Recent discussions focus on high-severity CVEs such as CVE-2026-7899 and CVE-2026-3926, which involve memory-safety flaws like out-of-bounds reads that can lead to sandboxed code execution via crafted HTML. These bugs are patched in Google Chrome and then ingested by Microsoft Edge, with Microsoft's Security Update Guide tracking when Edge builds receive the upstream fix. For Windows administrators, the key concern is how quickly Chromium risk propagates across browser estates, emphasizing the need for timely updates to mitigate potential exploitation.
