CVE-2026-7328
Média · 6.8
CWE-862 22/07/2026
Unverified AXI Address in Subsystem Mode Commands Enables Denial of Service
Missing authorization in Caliptra Core Runtime Firmware (INVOKE_DPE_MLDSA87, CM_AES_GCM_DECRYPT_DMA, EXTERNAL_MAILBOX_CMD commands) in subsystem mode allows a privileged local attacker to cause a denial of service via mailbox commands containing unverified AXI addresses. The security impact beyond availability is integration-specific.
This issue affects Core Runtime Firmware: 2.1.0.
CVE-2026-6458
Média · 5.1
CWE-325 23/06/2026
AES-256-GCM Authentication Tag Does Not Cover First Ciphertext Blocks When AAD Is Empty
Missing cryptographic step in Caliptra Core Firmware (aes_256_gcm_update module) results in an incorrect GCM authentication tag. When the streaming AES-256-GCM API is used with empty AAD, the hardware GHASH accumulator state is not saved after the first update call, causing the final tag to exclude the first batch of processed ciphertext. Ciphertext produced by that call may be modified without the tag reflecting the change.
This issue affects Core Runtime Firmware: from 2.0.0 through 2.0.1, 2.1.0.
CVE-2026-5818

CWE-253 23/06/2026
MCU Firmware Update Authentication Bypass on Caliptra Core
Incorrect check of function return value in Caliptra Core Runtime Firmware (ActivateFirmwareCmd::activate_fw modules) allows bypass of Caliptra Core's verification of the MCU FW during a hitless update.
This issue affects Core Runtime Firmware: from 2.0.0 through 2.0.1, 2.1.0.
