Last modified Jun 17, 2026

CVE-2025-55558 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. A buffer overflow occurs in pytorch v2.7.0 when a PyTorch model consists of torch.nn.Conv2d, torch.nn.functional.hardshrink, and torch.Tensor.view-torch.mv() and is compiled by Inductor, leading to a Denial of Service (DoS).. EPSS estimates a 0.42% chance of exploitation in the next 30 days.
