CVE-2025-52457
Observable Timing Discrepancy (CWE-208) in HBUS devices may allow an attacker with physical access to the device to extract device-specific keys, potentially compromising further site security.
Does this matter?
Lower severity and a low EPSS score (0.16%). Track it; it rarely justifies an emergency change on its own.
