Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel up to 5.3.11 (Operating System). This affects the function create_resource_pool of the file drivers/gpu/drm/amd/display/dc. The manipulation with an unknown input leads to a resource consumption vulnerability. CWE is classifying the issue as CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. This is going to have an impact on availability. The summary by CVE is:

Memory leaks in *create_resource_pool() functions under drivers/gpu/drm/amd/display/dc in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption). This affects the dce120_create_resource_pool() function in drivers/gpu/drm/amd/display/dc/dce120/dce120_resource.c, the dce110_create_resource_pool() function in drivers/gpu/drm/amd/display/dc/dce110/dce110_resource.c, the dce100_create_resource_pool() function in drivers/gpu/drm/amd/display/dc/dce100/dce100_resource.c, the dcn10_create_resource_pool() function in drivers/gpu/drm/amd/display/dc/dcn10/dcn10_resource.c, and the dce112_create_resource_pool() function in drivers/gpu/drm/amd/display/dc/dce112/dce112_resource.c, aka CID-104c307147ad.

The weakness was shared 11/18/2019. This vulnerability is uniquely identified as CVE-2019-19082 since 11/18/2019. The exploitability is told to be easy.
