Description
Description
In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau: fix u32 overflow in pushbuf reloc bounds check
nouveau_gem_pushbuf_reloc_apply() validates each relocation with
if (r->reloc_bo_offset + 4 > nvbo->bo.base.size)
but reloc_bo_offset is __u32 (uapi/drm/nouveau_drm.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 size_t bo size.
Cast to u64 so the addition happens in 64-bit arithmetic.
