Apple Fixes Groundbreaking Pointer Infoleak in macOS/iOS Serialization (2025)
In March 2025, Apple patched a novel vulnerability in macOS and iOS after research by Google Project Zero revealed a pointer information leak in the way Apple's Foundation framework handled serialization and deserialization via NSKeyedArchiver and NSKeyedUnarchiver. The flaw allowed attackers to deduce memory address information—specifically, the address of the NSNull singleton—by crafting serialized data and analyzing the ordering of keys upon re-serialization, without exploiting any memory corruption or timing attacks. This potential leak could subvert Address Space Layout Randomization (ASLR), a key memory protection mechanism, if leveraged in real-world attack surfaces that allow roundtripping of attacker-supplied serialized objects. Although the direct impact was mitigated by Apple’s 31 March 2025 security update, the disclosure highlights an overlooked class of pointer leak vulnerabilities inherent in pointer-keyed data structures, especially where object addresses serve as hash values. This incident is significant in the context of a broader industry trend: attackers are increasingly pursuing remote and non-traditional side channels for ASLR bypasses and memory leaks, while defenders must contend with the residual risks of serialization and legacy data structure design. Regulatory and customer pressure continues to rise for organizations to ensure modern memory safety, especially as zero trust and data segmentation architectures rely on robust underlying primitives.
