CVE-2026-74524

CVE-2026-74524 : In the Linux kernel (RISC‑V), a fix prevents an out‑of‑bounds page‑table walk during memory hot‑remove. When page‑table levels are folded (Sv48 Sv39), remove_pud_mapping/remove_p4d_mapping compute child bases with pud_offset(p4dp,0) / p4d_offset(pgd,0) and then add an index that ...

CVE-2026-72362

The CVE-2026-72362 issue affects the Linux kernel DRM/XE PT path (xe_pt_zap_ptes_entry). The vulnerability arises when a NULL child pointer for unpopulated entries is dereferenced because container_of(*child) is called before a NULL check, causing a crash. The fix moves the container_of() call af...

CVE-2026-72358

CVE-2026-72358 relates to the Linux kernel drm/xe/pt code, where cursor handling for purged BOs could be left uninitialized during page-table walks in xe_pt_hugepte_possible() and xe_pt_scan_64K(), leading to invalid cursor accesses and warnings. The fix adds an explicit purged-BO check (like NUL...
