Prior to 0.21.16, 0.22.2, and 0.23.1, tract-nnef uses unchecked usize multiplication in nnef/src/tensors.rs read_tensor for attacker-controlled tensor dimensions, the allocation size, and the reported tensor length. Loading a crafted NNEF archive through model_for_path or model_for_read reaches the default DatLoader and can make the wrapped size check accept a small allocation while data/src/tensor.rs as_slice_unchecked creates a much larger logical slice. Model construction through as_uniform can then read beyond the heap allocation and disclose adjacent data, and later access can terminate the process with a segmentation fault. The affected dense numeric tensor path does not include the independently guarded bool, String, or block-quant paths, and no out-of-bounds write or code execution was demonstrated. This issue is fixed in versions 0.21.16, 0.22.2, and 0.23.1.","state":0,"publishedAt":"2026-09-14T20:16:47.29+00:00","modifiedAt":"2026-09-30T17:51:56.193+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H","score":6.1,"severity":"MEDIUM"}],"references":["https://github.com/sonos/tract/commit/34c7df2c9bd2a36583e09b52f3e6319bf23102e8","https://github.com/sonos/tract/commit/828ec20f74c14c0923c7d7f0cff062ed222d630a","https://github.com/sonos/tract/commit/ee5f019d39fb97f7d4431b883c3ce97b74c28a64","https://github.com/sonos/tract/releases/tag/0.21.16","https://github.com/sonos/tract/releases/tag/0.22.2","https://github.com/sonos/tract/releases/tag/v0.23.1","https://github.com/sonos/tract/security/advisories/GHSA-x5mv-8wgw-29hg"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-55093","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-125","CWE-190"],"productCriteria":[],"sourceDates":{"published":"2026-09-14T20:16:47.290","lastModified":"2026-09-30T17:51:56.193"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
