A flaw was found in the Linux kernel's Direct Rendering Manager (DRM) subsystem, specifically within the TTM (Translation Table Manager) component. A local attacker with low privileges could exploit this vulnerability due to a resource leak that occurs during certain eviction errors. This could lead to a denial of service (DoS) condition, making the system unavailable.
