CVE-2025-23149

Estado: AnalizadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

tpm: do not start chip while suspended

Checking TPM_CHIP_FLAG_SUSPENDED after the call to tpm_find_get_ops() can lead to a spurious tpm_chip_start() call:

Don't move forward with tpm_chip_start() inside tpm_try_get_ops(), unless TPM_CHIP_FLAG_SUSPENDED is not set. tpm_find_get_ops() will return NULL in such a failure case.
