Stack overflow DoS via crafted message on Apple OSes
A stack overflow in Apple operating systems can be triggered by processing a maliciously crafted message and may cause a denial of service. The issue was fixed with improved input validation. Affected systems are those still running iOS, iPadOS, macOS, or visionOS builds earlier than the versions Apple lists as fixed.
What to do: Install Apple’s updates: iOS and iPadOS 26.7.2 or 27.2, macOS Sequoia 15.8.2, macOS Tahoe 26.7.2, macOS Golden Gate 27.2, and visionOS 27.2.

| Apple iPadOS | — | 26.7.2, 27.2 |
| Apple macOS Golden Gate | — | 27.2 |
