search for: local_buffer

Hi, Yeah, now I understand the problem here. Thanks. But I too have another doubt in "Bounds check bypass store" In this example in the Speculative load hardening : unsigned char local_buffer[4];unsigned char *untrusted_data_from_caller = ...;unsigned long untrusted_size_from_caller = ...;if (untrusted_size_from_caller < sizeof(local_buffer)) { // Speculative execution enters here with a too-large size. memcpy(local_buffer, untrusted_data_from_caller, untrusted_size_from...

Hi, Thanks for your email, I understand that the execution stalls until the predicated state is computed, then we mask pointers with all_zeros_mask if there is a mis-prediction. But I understand that as soon as the condition value is available, the processor can check about it's assumptions and revert back. That is, If the branch prediction is correct during speculation, we mask with
