CVE-2024-41011

Local GPU register exposure via oversized MMIO mapping

Published Jul 18, 2024 · Updated Aug 5, 2026

Incorrect MMIO mapping in Linux 5.3 through 6.9-rc3 allows local users to access unintended GPU register space through AMD KFD. In kfd_chardev.c, kfd_mmio_mmap and two allocation or restore paths map PAGE_SIZE bytes from a 4 KiB HDP register-remap window without rejecting larger kernel page sizes. Exploitation requires local KFD access, an AMD GPU exposing the remap window, and a kernel page size above 4 KiB; the extra mapping exposes adjacent MMIO registers.
