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. On WindowsForum.com, recent discussions cover multiple use-after-free flaws patched in Chrome 150 and Microsoft Edge, including bugs in Chromium's Oilpan garbage collector, Views interface, Scheduling component, WebProtect, Chrome Updater, PageInfo, and Passwords. These vulnerabilities affect Windows, macOS, Android, and Linux, often allowing remote code execution or privilege escalation. A recurring theme is the mismatch between Chromium's low or medium severity labels and higher CVSS scores from CISA or NVD, highlighting the need for administrators to assess risk beyond vendor ratings. Practical advice includes updating to Chrome 150.0.7871.47 or Edge 150.0.4078.48 and understanding exploit chains.
