  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/vmwgfx: use check_add_overflow for shader size+offset bound  vmw_shader_define() validates the user-supplied shader window against its backing buffer with  \t(u64)buffer-\u003etbo.base.size \u003c (u64)size + (u64)offset  drm_vmw_shader_create_arg::offset is __u64 in the uapi; when it is near U64_MAX the unsigned addition wraps and the resulting tiny value passes the check.  The unbounded offset is then stored in res-\u003eguest_memory_offset and forwarded to host SVGA shader-create commands.  Use check_add_overflow() to detect the wrap and compare the resulting endpoint against the buffer size.",
