Overview

CVE-2026-72095 is a high-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

dma-fence: Make dma_fence_dedup_array() robust against 0-count input

dma_fence_dedup_array() returns 1 when called with num_fences == 0:

the for-loop body never executes, j stays at 0, and the final

`return ++j` yields 1. This contradicts both the kernel-doc ("Return:

Number of unique fences remaining in the array") and the natural

expectation that 0 input gives 0 output.

The caller __dma_fence_unwrap_merge() bails out via the

`if (count == 0 || count == 1)` fast path and so is save.

But amdgpu_userq_wait_*() could reach the dedup call with a zero local

count and dereference an uninitialized fence slot in the array.

Make the contract match the documentation by returning 0 early. This

also skips an unnecessary sort() call on an empty array.

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.
