Some Call of Duty: Warzone players report a security attestation bug that incorrectly demands a BIOS firmware update despite their systems meeting all compliance checks, including TPM 2.0 and Secure Boot. This false positive restricts affected players to casual Battle Royale mode, preventing access to ranked and other competitive playlists. The issue causes frustration by limiting gameplay options for those with fully compliant hardware. Developers are expected to address this mismatch to restore full mode access and ensure fair play.
