the Linux kernel, the following vulnerability has been resolved:\n\nchar: tpm: Protect tpm_pm_suspend with locks\n\nCurrently tpm transactions are executed unconditionally in\ntpm_pm_suspend() function, which may lead to races with other tpm\naccessors in the system.\n\nSpecifically, the hw_random tpm driver makes use of tpm_get_random(),\nand this function is called in a loop from a kthread, which means it's\nnot frozen alongside userspace, and so can race with the work done\nduring system suspend:\n\n  tpm tpm0: tpm_transmit: tpm_recv: error -52\n  tpm tpm0: invalid TPM_STS.x
