Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.3.11
Description
The issue is related to memory leaks in the
create resource pool() functions under drivers/gpu/drm/amd/display/dc in the Linux kernel. This affects several functions, including dce120 create resource pool(), dce110 create resource pool(), dce100 create resource pool(), dcn10 create resource pool(), and dce112 create resource pool(). The memory leaks can be exploited by attackers to cause a denial of service due to memory consumption.Recommendations
For Linux kernel versions prior to 5.3.11, update to a version 5.3.11 or later to resolve the issue. As a temporary workaround, consider restricting access to the affected
create resource pool() functions to minimize the risk of exploitation.Fix
