Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

A heap buffer overflow in how ExecuTorch loads models affects the org.pytorch:executorch-android Maven package and the PyPI executorch package before version 0.7.0. The source does not say what an attacker must provide or whether any user action is needed, but it states that exploitation can lead to code execution or other undesirable effects. Upgrade to version 0.7.0 or later, which is the listed fixed version for both packages.
