Description

A flaw was found in the Linux kernel's drm/xe/vm module. During the creation of a virtual machine (VM), an error in resource allocation could lead to a Shared Virtual Memory (SVM) resource leak. This occurs because the kernel's resource deallocation functions are not consistently called when an error happens. A local attacker could exploit this to exhaust system resources, potentially leading to a Denial of Service (DoS).
