Vulnerability from github – Published: 2026-08-15 06:32 – Updated: 2026-08-23 15:33
VLAI
Details

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.
