CVE-2025-54505 is a transient-execution information-disclosure vulnerability affecting certain AMD processors. Floating-point divider-unit data is not properly cleared during speculative execution, allowing residual data associated with prior floating-point division operations to be sampled through a microarchitectural side channel. The issue is also referred to as Floating Point Divider State Sampling.
