CVE-2026-72152

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:

1. Call wait_tpm_stat_cond() only while tasking is running.

2. Use wait_woken() to wait for changes.
