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 Linux kernel CVE team has assigned CVE-2026-72152 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/char/tpm/tpm_tis_core.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/c9acbe38797bc1aa3c22a1ab72452e210af6e0ff https://git.kernel.org/stable/c/6b068a97958aa00a901a9b5083d74114b21f7b66 https://git.kernel.org/stable/c/bb63a0530e8e6de3aaf29cd5ba487db2490128ef https://git.kernel.org/stable/c/ba33b4f9d3423accd2c91a0b0b0680cd589922f2 https://git.kernel.org/stable/c/4bb3e1bc142dc9c3240ceed1b3ab031aa9cb1723 https://git.kernel.org/stable/c/c0c9cfb3b75def8bf200a2d4db09015806acfeaf
