CVE-2024-46694: drm/amd/display: avoid using null object of framebuffer
First published: Fri Sep 13 2024(Updated: )
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: avoid using null object of framebuffer Instead of using state->fb->obj[0] directly, get object from framebuffer by calling drm_gem_fb_get_obj() and return error code when object is null to avoid using null object of framebuffer. (cherry picked from commit 73dd0ad9e5dad53766ea3e631303430116f834b3)
