Description
A flaw was found in the Linux kernel's drm/xe subsystem. When handling dma-buf attachments, a resource leak occurs if the initialization of a dma-buf object fails, as the attachment is not properly detached. This oversight can lead to resource exhaustion, potentially allowing a local attacker to cause a Denial of Service (DoS) by making the system unstable or unresponsive.
