CVE-2026-0714 is a medium-severity flaw (CVSS 6.8) affecting uc-1222a firmware, uc-2222a-t-us firmware, uc-2222a-t firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
A physical attack vulnerability exists in certain Moxa industrial computers using TPM-backed LUKS full-disk encryption on Moxa Industrial Linux 3, where the discrete TPM is connected to the CPU via an SPI bus. Exploitation requires invasive physical access, including opening the device and attaching external equipment to the SPI bus to capture TPM communications. If successful, the captured data may allow offline decryption of eMMC contents. This
