Description SMASH SMASH 2024-05-22 14:58:39 UTC

In the Linux kernel, the following vulnerability has been resolved:

drm: vmwgfx_surface.c: copy user-array safely

Currently, there is no overflow-check with memdup_user().

Use the new function memdup_array_user() instead of memdup_user() for
duplicating the user-space array safely.

Comment 1 Michal Hocko 2024-05-24 12:11:17 UTC

As pointed by Jiri Bohac, this is not really necessary as the range check is done properly here.

Close as INVALID.
