Description
A flaw was found in the Linux kernel's AMD GPU (amdgpu) driver. Specifically, a reference leak occurs in the `amdgpu_userq_wait_ioctl` function. This issue arises when an I/O control (ioctl) operation is aborted because the output array provided is insufficient. A local attacker could exploit this to cause resource exhaustion, leading to a denial of service (DoS) on the system.
