CVE-2022-32912Network attack vector

Code execution via WebGL2 out-of-bounds read

Published Sep 20, 2022 · Updated Jan 7, 2026

Out-of-bounds read in Apple WebKit allows remote attackers to execute code through malicious web content in Safari and iOS. WebGL2 drawRangeElements fails to validate supplied values before reading past the end of an allocated buffer. Exploitation requires opening a malicious page or file; the direct result is process-memory disclosure, while code execution requires a vulnerability chain.
