CVE-2024-42275

Local kernel compromise via false-success mapping return

Published Aug 17, 2024 · Updated Aug 5, 2026

Uninitialized pointer access in the Linux kernel 6.10 through 6.10.3 allows local users with graphics access to compromise the kernel. drm_client_buffer_vmap_local() returns success after drm_gem_vmap() fails, leaving map_copy uninitialized and the reservation lock state inconsistent. Access to fbdev and DRM render nodes permits forced mapping failure followed by framebuffer damage that writes through the invalid map, causing memory corruption, kernel panic, or deadlock.
