CVE-2026-8541Network attack vector

Memory disclosure via UI out-of-bounds read

Published May 14, 2026 · Updated May 14, 2026

Out-of-bounds read in Google Chrome UI before 148.0.7778.168 allows remote attackers to disclose process-memory data via crafted HTML. Google identifies the UI component and memory-boundary failure, but the restricted Chromium issue does not disclose the specific code locus or invalid read operation. Exploitation requires prior renderer-process compromise and user interaction with the crafted page; the reported consequence is memory disclosure only.
