Sensitive information disclosure via WebKit out-of-bounds read
Published Jun 23, 2023 · Updated Dec 5, 2024
An out-of-bounds read in WebKit on affected Apple platforms allows remote attackers to disclose sensitive information via web content. Apple identifies WebKit as the locus but has not published the malformed input, parser path, or read operation that crosses a memory boundary. Exploitation requires processing attacker-controlled web content and is limited to information disclosure; no integrity or availability impact is reported.
