A newly discovered vulnerability in Apple's M series chips may lead to wallet key leakage

ChainCatcher news, according to Ars Technica, a newly discovered vulnerability in Apple's M series chips may lead to wallet key leakage. This vulnerability is a side channel that allows end-to-end key extraction when Apple chips run encrypted wallets, but this flaw cannot be directly patched as it originates from the microarchitecture design of the chip itself. Instead, it can only be mitigated by establishing defenses in third-party encryption software, which significantly reduces the performance of the M series, especially in the earlier M1 and M2 generation products. The vulnerability is exploited when the target encryption operation runs on the same CPU cluster as a malicious application with normal user system privileges.
