OpenUSD does contain code bundled from OpenEXR 3.2.0, which per https://www.cve.org/CVERecord?id=CVE-2025-64183 is one of the versions that contained the vulnerable PyObject_StealAttrString implementation. However, OpenUSD only contains a subset of OpenEXR, and the PyObject_StealAttrString function is not included; therefore, the usd package is not affected by this CVE.
