Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A memory leak exists in the AMD Direct Rendering Infrastructure (DRI) driver within the Linux kernel. The issue occurs in the dcn30 clock source create() function located in the drivers/gpu/drm/amd/display/dc/dcn314/dcn314 resource.c module. When the initialization logic encounters an error and reaches the final return NULL path, the memory allocated for the clk src structure is not properly freed. This accumulation of leaked memory during repeated initialization attempts can lead to resource exhaustion and a denial of service.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
