A flaw was found in the Linux kernel's Nouveau graphics driver. When destroying a GPU scheduler object, the driver frees memory prematurely while user-space synchronization objects still hold references to it. A local, unprivileged user could exploit this flaw by querying synchronization file information to trigger a use-after-free read, potentially leading to a system crash and Denial of Service (DoS) or information disclosure.
