  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/vmwgfx: validate DRAW_PRIMITIVES header size before division  vmw_cmd_draw() computes  \tmaxnum = (header-\u003esize - sizeof(cmd-\u003ebody)) / sizeof(*decl);  where header-\u003esize is u32 and is taken straight from the user-supplied command stream.  When header-\u003esize is less than sizeof(cmd-\u003ebody) the unsigned subtraction wraps to nearly 4 GiB, producing a huge maxnum. Any user-controlled cmd-\u003ebody.numVertexDecls then passes the bound and the loop dereferences decl[i] far past the end of the kernel command bounce buffer, producing an out-of-bounds read of kernel memory.  Reject undersized headers up front.",
