Process-memory disclosure via GPU out-of-bounds read
Published May 20, 2026 · Updated May 20, 2026
Out-of-bounds read in Google Chrome for Mac before 148.0.7778.179 allows remote attackers to read process memory via crafted HTML. Chrome's GPU component reads beyond an allocated memory boundary while processing the page, but Google has not disclosed the affected function or malformed field. Successful exploitation requires a Mac user to load the attacker-controlled page; the reported consequence is process-memory disclosure without data modification or service interruption.
