Summary
drm/nouveau: fix u32 overflow in pushbuf reloc bounds check
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/nouveau: fix u32 overflow in pushbuf reloc bounds check

nouveaugempushbufrelocapply() validates each relocation with

if (r->reloc_bo_offset + 4 > nvbo->bo.base.size)

but relocbooffset is __u32 (uapi/drm/nouveaudrm.h) and the integer literal 4 promotes to unsigned int, so the addition is performed in 32 bits and wraps before the comparison against the sizet bo size.

Cast to u64 so the addition happens in 64-bit arithmetic.
