Vulnerability from github – Published: 2026-07-23 18:31 – Updated: 2026-07-23 18:31

Details

PyTorch torchvision through 0.28.0, fixed in commit 4e05dc2, contains an out-of-bounds heap read vulnerability in the GIF decoder's read_from_tensor callback that passes unclamped length to memcpy. Attackers can supply malicious or truncated GIF files to cause denial of service via segmentation fault or disclose adjacent heap memory contents.

Severity

7.1 (High)
