How to fix?

Upgrade SLES:15.7 kernel-livepatch-6_4_0-150700_53_90-default to version 1-150700.15.3.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-6_4_0-150700_53_90-default package and not the kernel-livepatch-6_4_0-150700_53_90-default package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

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.
