About this tag
Use-after-free is a memory corruption vulnerability where a program continues to use a pointer after the memory it points to has been freed, often leading to crashes or arbitrary code execution. On WindowsForum.com, discussions focus on recent Chromium-based browser CVEs affecting Microsoft Edge and Google Chrome, including CVE-2026-12462 in Edge's Chromium engine and multiple Chrome flaws (CVE-2026-11647, CVE-2026-11700, CVE-2026-11692, CVE-2026-11683, CVE-2026-11673, CVE-2026-11671) disclosed in June 2026. These use-after-free bugs reside in components like Printing, Tracing, Read Anything, WebCodecs, InterestGroups, and Navigation, often enabling sandbox escapes or remote code execution via crafted HTML pages. For Windows administrators and users, patching to Chrome 149.0.7827.103 or the latest Edge update is critical to mitigate these risks.
