The vulnerability occurs when a blocked donor that is migration‑disabled is incorrectly flagged by set_task_cpu(), producing a warning that a blocked scheduling context was moved. The kernel incorrectly assumes the donor can be migrated, but the donor remains on its original CPU. The warning is a false positive, leading only to misleading logs and potential misdiagnosis, not exploitation.

The issue is present in the Linux kernel core scheduling code, affecting all Linux‑based operating systems that use the unmodified kernel source up to the current unreleased version. No specific vendor or product version is enumerated; the affected product is Linux:Linux.

The CVSS score is 4.7, indicating moderate severity, and based on the description it is inferred that the bug does not contain a direct attack vector; no evidence of exploitation has been reported, and the EPSS score is < 1% while it is not listed in KEV. The likelihood of real‑world exploitation appears low. However, the false warning could disturb automated monitoring or cause confusion for system administrators.
