CVE-2025-63396: n/a
An issue was discovered in PyTorch v2.5 and v2.7.1. Omission of profiler.stop() can cause torch.profiler.profile (PythonTracer) to crash or hang during finalization, leading to a Denial of Service (DoS).
AI Analysis
Technical Summary
CVE-2025-63396 describes a denial of service vulnerability in PyTorch versions 2.5 and 2.7.1. When the profiler.stop() function is omitted, the torch.profiler.profile component using PythonTracer may crash or hang during its finalization phase. This leads to an application-level denial of service due to improper handling of the profiler lifecycle.
Potential Impact
The impact is limited to denial of service caused by application crashes or hangs during profiler finalization. There is no confidentiality or integrity impact reported. The vulnerability requires local access with low privileges and no user interaction is needed.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. In the meantime, ensure that profiler.stop() is properly called to avoid triggering the issue.
