CVE-2019-19927

An out-of-bounds (OOB) memory access flaw was found in ttm_put_pages in drivers/gpu/drm/ttm/ttm_page_alloc.c in the Linux kernel’s graphics module. Incrementing the page pointer for huge pages was not in sync with the reference counter, and this could lead to an out-of-bounds access or a denial of service. This flaw allows a local attacker with special user privileges (or root) to cause memory exploitation.
