CVE-2026-63950

Summary: CVE-2026-63950 pertains to the Linux kernel mm/rmap path. The issue arose from not reinitializing nr_pages at the start of each loop in try_to_unmap_one, allowing a value from a previous folio_unmap_pte_batch() to be reused in a later iteration. This could cause corruption of folio refco...
