CVE-2021-42327

dplinksettingswrite in drivers/gpu/drm/amd/display/amdgpudm/amdgpudmdebugfs.c in the Linux kernel through 5.14.14 allows a heap-based buffer overflow by an attacker who can write a string to the AMD GPU display drivers debug filesystem. There are no checks on size within parsewritebufferintoparams when it uses the size of copyfromuser to copy a userspace buffer into a 40-byte heap buffer.
