Sources and claim methodology

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: tpm: tpm_i2c_nuvoton: disable IRQ on wait timeout i2c_nuvoton_wait_for_stat() enables the IRQ before waiting for the interrupt handler to report a status change. If the wait times out, or is interrupted before the handler runs, the function returns without balancing the enable_irq() call. Disable the IRQ before leaving the failed wait path. Also preserve an interrupted wait's original error code instead of converting it to -ETIMEDOUT inside the helper.
