Technical description

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

nouveau/uvmm: fix addr/range calcs for remap operations

dEQP-VK.sparse_resources.image_rebind.2d_array.r64i.128_128_8

was causing a remap operation like the below.

op_remap: prev: 0000003fffed0000 00000000000f0000 00000000a5abd18a 0000000000000000

op_remap: next:

op_remap: unmap: 0000003fffed0000 0000000000100000 0

op_map: map: 0000003ffffc0000 0000000000010000 000000005b1ba33c 00000000000e0000

This was resulting in an unmap operation from 0x3fffed0000+0xf0000, 0x100000

which was corrupting the pagetables and oopsing the kernel.

Fixes the prev + unmap range calcs to use start/end and map back to addr/range.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
