"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/vmwgfx: use check_add_overflow for shader size+offset bound\n\nvmw_shader_define() validates the user-supplied shader window against\nits backing buffer with\n\n\t(u64)buffer->tbo.base.size < (u64)size + (u64)offset\n\ndrm_vmw_shader_create_arg::offset is __u64 in the uapi; when it is\nnear U64_MAX the unsigned addition wraps and the resulting tiny value\npasses the check. The unbounded offset is then stored in\nres->guest_memory_offset and forwarded to host SVGA shader-create\ncommands.\n\nUse check_add_overflow() to detect the wrap and compare the resulting\nendpoint against the buffer size."
