kernel: Linux kernel: Denial of Service due to a deadlock in hugetlb folio migration

A flaw was found in the Linux kernel. A local attacker could exploit a deadlock vulnerability due to incorrect lock ordering between foliolock and immaprwsem when migrating hugetlb file-backed folios. This could lead to hung tasks and potential system-wide stalls, resulting in a Denial of Service...
