Sama5D4
Monthly
Hardware fault injection via voltage and clock glitching in the Microchip SAMA5D4 ARM Cortex-A5 microprocessor enables a physically proximate attacker to subvert security-critical operations such as secure boot, cryptographic key protection, and privilege enforcement. All versions of the SAMA5D4 are affected per the vendor's CPE entry, and Microchip self-reported this vulnerability. No public exploit code has been identified and CISA has not added this to the KEV catalog, but the all-high impact scores in the CVSS 4.0 vector (VC:H/VI:H/VA:H/SC:H/SI:H/SA:H) reflect that successful exploitation grants total control over the affected system and any downstream components it secures.
