AZL-101499 CVE-2026-89987 affecting package kernel 6.6.150.1-1

In the Linux kernel, the following vulnerability has been resolved: mm/hugememory: transfer the pmd dirty bit to the folio on zap zaphugepmdfolio propagates the pmd young bit to the folio for the file case, but not the dirty bit. The pte path does propagate it, in zappresentfolioptes and so does...

CVE-2026-89987

CVE-2026-89987 affects the Linux kernel in the mm/huge_memory subsystem. The function zap_huge_pmd_folio() fails to propagate the PMD dirty bit to the folio when a PMD-mapped shmem/tmpfs page is unmapped, unlike the PTE path and PMD split path. This causes silent data loss for processes that stor...

CVE-2026-80729

CVE-2026-80729 affects the Linux kernel in the mm/huge_memory subsystem. The root cause is that __folio_split() leaves the xa_state's xa_lru field unset, while xas_try_split() adds __GFP_ACCOUNT for page-cache xa_nodes. This allows a live, memcg-charged xa_node to exist without being linked into ...
