CVE-2026-93218

The Linux kernel contains a vulnerability in the mm/huge_memory component related to how it handles device-private Page Middle Directories (PMDs). A race condition occurs when an HMM-based GPU driver interacts with madvise(MADV_FREE). Specifically, migrate_vma_pages() can flip a PMD to a device-p...

CVE-2026-93217

The Linux kernel contains a vulnerability in mm/madvise where madvise_cold_or_pageout_pte_range() can trigger a kernel panic. The issue occurs because pmd_is_huge() returns true for device-private PMDs, causing a VM_BUG_ON() assertion to trip when the PMD is not present. This is potentially trigg...
