Local ASLR bypass via Audio bounds error
Published Nov 12, 2025 · Updated Nov 12, 2025
Out-of-bounds access in Apple Audio allows local users to bypass ASLR across affected Apple operating systems. Apple identifies the locus only as Audio and has not disclosed which bounds check fails or what data is read outside its valid range. Exploitation requires a locally running app; the documented consequence is loss of address randomization rather than direct code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
