Apple’s latest chip generations are vulnerable to two critical side-channel attacks, FLOP and SLAP, which exploit speculative execution. These vulnerabilities can lead to unauthorized access to sensitive information from applications like Chrome and Safari, revealing credit card details, locations, and more. FLOP targets the load value predictor to expose memory content while SLAP uses the load address predictor to access incorrect memory addresses. Both attacks demonstrate security risks that accompany performance enhancements in CPU design, emphasizing the need for cautious implementation of speculative execution tactics.
The vulnerabilities in Apple's A- and M-series chip sets allow unauthorized remote access, potentially compromising sensitive data including credit card information and location data.
FLOP exploits the load value predictor to gain access to restricted memory contents while SLAP manipulates the load address predictor to retrieve incorrect memory locations.
