In the Linux kernel, the following vulnerability has been resolved: tpm: tpm_tis_spi: Use wait_woken() in wait_for_tmp_stat() wait_event_interruptible_timeout() evaluates its condition after setting the current task state to TASK_INTERRUPTIBLE. With CONFIG_DEBUG_ATOMIC_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:
- Call wait_tpm_stat_cond() only while tasking is running.
- Use wait_woken() to wait for changes.
A flaw was found in the Linux kernel's Trusted Platform Module (TPM) TIS SPI driver. Thewait_event_interruptible_timeout()function incorrectly evaluates its condition after setting the task state, which can trigger a warning when debugging atomic sleeps and using the Interrupt Request (IRQ) wait path. This could potentially lead to system instability or unexpected behavior. The issue has been resolved by implementing proper task state handling and usingwait_woken()for changes.
