CVE-2026-89756
CVE-2026-89756 is a Linux kernel flaw in migrate_pages_batch() (mm/migrate). On PREEMPTION kernels, the loop's cond_resched() call is a no-op, and involuntary preemption does not constitute a Tasks-RCU quiescent state . When large page-migration batches run on KVM hosts , the expensive tdp_mmu_za...

CVE-2026-89757
CVE-2026-89757 affects the Linux kernel 's multi-gen LRU (mglru) subsystem. The root cause is a buggy shortcut in sort_folio() for handling unevictable folios: it fails to initialize mlock_count , causing it to alias LIST_POISON2 (value 290). As a result, __munlock_folio() cannot clear the PG_mlo...

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...
