Description SMASH SMASH 2024-05-24 15:46:49 UTC

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

drm_lease.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.
