SUSE CVE-2026-43497

In the Linux kernel, the following vulnerability has been resolved: fbdev: udlfb: add vmops to dlfbopsmmap to prevent use-after-free dlfbopsmmap uses remappfnrange to map vmalloc framebuffer pages to userspace but sets no vmops on the VMA. This means the kernel cannot track active mmaps. When...

CVE-2026-43497

The CVE-2026-43497 issue affects the Linux kernel fbdev path (udlfb/dlfb) where dlfb_ops_mmap maps vmalloc framebuffer pages without vm_ops, preventing mmap tracking. This allowed stale user PTEs to coexist with freed kernel pages after dlfb_realloc_framebuffer() via FBIOPUT_VSCREENINFO, causing ...
