In the Linux kernel, the following vulnerability has been resolved:
tpm: tpmtisspi: Use waitwoken() in waitfortmpstat()
waiteventinterruptibletimeout() evaluates its condition after setting the current task state to TASKINTERRUPTIBLE.
With CONFIGDEBUGATOMIC_SLEEP this triggers a warning when the IRQ wait path is used:
tpm_tis_status()
tpm_tis_spi_read_bytes()
tpm_tis_spi_transfer_full()
spi_bus_lock()
mutex_lock()
Address this with the following measures:
