CVE-2022-36402 is an integer overflow vulnerability in the vmwgfx driver (drivers/gpu/vmxgfx/vmxgfx_execbuf.c) of the Linux kernel. The vulnerability is triggered via the device file '/dev/dri/renderD128' (or similar), where improper handling of integer values can lead to an overflow. This flaw can be exploited by a local attacker with a user account to execute code with elevated privileges or cause a denial of service (DoS).
