Description
A flaw was found in the Linux kernel's AMD GPU driver. When registering hardware discovery entries within the sysfs (system filesystem) interface, the driver fails to release allocated memory if a kernel object fails to register. An unexpected registration failure can cause the memory to remain uncollected, leading to a memory leak and a potential Denial of Service (DoS) due to resource exhaustion.
