• [$] Protecting against TPM interposer attacks

    From LWN.net@86:200/23 to All on Tue Apr 7 06:40:09 2026
    The Trusted
    Platform Module (TPM) is a widely misunderstood piece of hardware (or
    firmware) that lives in most x86-based computers. At SCALE 23x in Pasadena, California,
    James Bottomley gave a presentation on the TPM and the work that he and
    others have done to enable the Linux kernel to work with it. In
    particular, he described the problems with interposer attacks, which target
    the communication between the TPM and the kernel, and what has
    been added to the kernel to thwart them.
