Process crash or memory disclosure via crafted file
Published Sep 14, 2026 · Updated Sep 14, 2026
Out-of-bounds reading in affected Apple operating systems allows attackers to crash a process or disclose its memory by opening a crafted file. Apple has not identified the affected file parser or field; it states only that insufficient input validation permits an out-of-bounds read. Exploitation requires the crafted file to be opened, and the bounded consequences are process termination or disclosure of process memory.
