Linux Kernel up to 7.1.4 tpm_tis_spi wait_for_tmp_stat race condition

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Linux Kernel up to 6.1.177/6.6.144/6.12.96/6.18.39/7.1.4. It has been classified as very critical. Affected is the function wait_for_tmp_stat of the component tpm_tis_spi. The manipulation with an unknown input leads to a race condition vulnerability. CWE is classifying the issue as CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2026-72152 since 08/09/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 08/15/2026).

Upgrading to version 6.1.178, 6.6.145, 6.12.97, 6.18.40, 7.1.5 or 7.2-rc1 eliminates this vulnerability. Applying the patch c9acbe38797bc1aa3c22a1ab72452e210af6e0ff/6b068a97958aa00a901a9b5083d74114b21f7b66/bb63a0530e8e6de3aaf29cd5ba487db2490128ef/ba33b4f9d3423accd2c91a0b0b0680cd589922f2/4bb3e1bc142dc9c3240ceed1b3ab031aa9cb1723/c0c9cfb3b75def8bf200a2d4db09015806acfeaf is able to eliminate this problem.
