Doc Text:
A flaw was found in the NVIDIA GPU Display Driver open-source kernel module. An unprivileged local attacker can exploit improper preservation of memory access permissions during Direct Memory Access (DMA) mapping, which controls how the graphics hardware accesses system memory. Successful exploitation could allow the attacker to achieve privilege escalation, execute arbitrary code, expose or modify sensitive data, or cause a denial of service (DoS).
