CVE-2025-33244
Deserialization flaw in NVIDIA APEX for Linux (PyTorch <2.6) enables RCE.
Is CVE-2025-33244 being exploited?
Not confirmed. CVE-2025-33244 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly.

Patch when possible
- affectedAll versions that do not include commit db8e053
As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
