CVE-2025-38288

/// Technical description

In the Linux kernel, the following vulnerability has been resolved:

scsi: smartpqi: Fix smp_processor_id() call trace for preemptible kernels

Correct kernel call trace when calling smp_processor_id() when called in

preemptible kernels by using raw_smp_processor_id().

smp_processor_id() checks to see if preemption is disabled and if not,

issue an error message followed by a call to dump_stack().

Brief example of call trace:

kernel: check_preemption_disabled: 436 callbacks suppressed

kernel: BUG: using smp_processor_id() in preemptible [00000000]

code: kworker/u1025:0/2354

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
