CVE-2026-72152

Estado: RecibidaSin puntuar—

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:

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.
