Description
A flaw was found in the Linux kernel's AMD ISP4 driver. When allocating GPU memory, the isp4if_alloc_fw_gpumem() function fails to release partially allocated memory pools if an error occurs during the process. This memory leak could lead to system instability or a Denial of Service (DoS) over time, as available memory is gradually consumed.
