CVE-2026-89985

CVE-2026-89985 is a vulnerability in the Linux kernel's memory cgroup (memcg) subsystem . The root cause is a broken invariant in memcg_reparent_objcgs(): when a folio migrates across NUMA nodes, it inherits the old node's objcg, which desynchronizes objcg reparenting from LRU list reparenting. T...

CVE-2026-89755

CVE-2026-89755 affects the Linux kernel's device page migration subsystem (mm/migrate_device). The root cause is a stale folio mapping that persists after folio_free_swap() removes a folio from the swap cache. Passing this stale mapping to folio_migrate_mapping() causes the kernel to take the wro...

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...
