CVE-2025-68292

The CVE-2025-68292 issue concerns the Linux kernel memfd hugetlb folio allocation. A path used by memfd bypassed the normal page fault handler (hugetlb_no_page), omitting three initialisation steps that could leak kernel memory or cause races: (1) folios not zeroed, risking information disclosure...

kernel: iommufd: Fix race during abort for file descriptors

A flaw was found in the Linux kernel such that the IOMMU file-descriptor subsystem, when aborting the allocation of a new object before installing the file descriptor, the code calls fput on the file and then immediately frees the associated object kfree, but the object is still referenced by the...

CVE-2025-40249

CVE-2025-40249 affects the Linux kernel GPIO cdev path. The issue arises when a GPIO change notification is emitted after the file descriptor’s reference count drops to zero but before the .release() callback is executed from the workqueue, leaving the descriptor potentially in use-after-free. Th...
