CVE-2026-53207

The CVE-2026-53207 issue affects the Linux kernel mm/memory-failure path, where concurrent MADV_HWPOISON calls on the same hugetlb page can deadlock the non-recursive hugetlb_lock. The root cause is a sequence where a GUP reference is dropped under the hugetlb_lock, allowing free_huge_folio to re...

CVE-2026-53108

CVE-2026-53108 concerns a race in PowerPC64 (book3s64) PMD migration handling during unmap vs move_pages. The vulnerability arises when a PMD migration entry is created by migrate_pages while an munmap occurs, hitting a VM_BUG_ON in pmdp_huge_get_and_clear_full. The Linux kernel patch (commit a30...

PT-2026-52002

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A race condition exists in the Linux kernel for powerpc/64s architectures during the unmapping of Page Middle Directory PMD migration entries. The issue occurs when a move pages system...

CVE-2026-31597

The CVE-2026-31597 vulnerability affects the Linux kernel OCFS2 code. A use-after-free occurs in ocfs2_fault() when VM_FAULT_RETRY triggers after filemap_fault() drops mmap_lock, allowing a concurrent munmap() to free the vm_area_struct and causing ocfs2_fault() to dereference a dangling vma. The...

CVE-2026-23361

CVE-2026-23361 affects the Linux kernel PCIe design (dwc: ep) where a posted MSI-X write may race with ATU unmapping, potentially corrupting host memory or triggering IOMMU errors. The mitigation described in the public description is to flush the write by performing a readl() on the same address...
