A critical vulnerability (CVE-2025-27840) has been discovered in the ESP32 chip, which is widely used in Bitcoin hardware wallets like Blockstream Jade. The flaw stems from insufficient entropy in the chip's random number generator, making it possible for attackers to brute-force key pairs or exploit module updates to sign unauthorized transactions. This vulnerability poses a serious risk of Bitcoin theft, especially if not addressed through firmware patches or hardware-level security enhancements.
