Description
A flaw was found in the Linux kernel's AMDGPU driver. This vulnerability allows a local attacker to cause a Denial of Service (DoS) through kernel memory exhaustion. When command submission operations fail during certain error-handling paths, allocated memory ranges and buffer object references are not properly freed. By repeatedly submitting requests that trigger these failure conditions, an attacker can continuously leak memory until system resources are depleted.
