CVE-2026-72152 is a vulnerability of currently unknown severity. 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. EPSS estimates a 0.21% chance of exploitation in the next 30 days.
