CVE-2024-50017

CVE-2024-50017 affects the Linux kernel’s identity-mapping code (x86/mm/ident_map). When ident_pud_init() creates identity maps using only GB pages, it can map large address ranges not requested (a 4K request could yield a full 1GB mapping), potentially including BIOS-reserved areas. This enables...

CVE-2024-49964

The CVE-2024-49964 issue affects the Linux kernel’s hugetlb path: memfd_pin_folios + unpin_folios could fail to restore free_huge_pages for pages not faulted in due to folio refcounts not reaching zero. The root cause was that folio_ref_unfreeze/folio_try_get/hugetlb_add_to_page_cache interaction...

CVE-2024-49902

CVE-2024-49902 in the Linux kernel affects the JFS dmmap path. The root cause is an out-of-bounds condition in dbSplit when dmt_leafidx exceeds the number of leaves per dmap tree; a bounds check was added in dbFindLeaf. Shaggy’s change also extends the sanity check to cover control pages in addit...
