CVE-2026-89447

CVE-2026-89447 affects the Linux kernel iommufd subsystem. In iommufd_access_notify_unmap() , the code calls iommufd_lock_obj() before checking whether the access is internal. When the access is internal, the loop skips it via continue, bypassing the matching iommufd_put_object() call used by the...

CVE-2026-68240

Summary: CVE-2026-68240 affects the Linux kernel drm/gpusvm component. The root cause was that drm_gpusvm_get_pages() on an error path did not correctly assign svm_pages->dpagemap, causing __drm_gpusvm_unmap_pages() to skip device_unmap() and leak device mappings that had already been created....
