Description Mauro Matteo Cascella 2023-07-12 15:15:22 UTC
OSS-Fuzz reported a use-after-free issue in e1000e. This looks similar to https://gitlab.com/qemu-project/qemu/-/issues/1543. However, Alexander Bulekov confirmed that this crashes both on master and v8.0 (albeit with slightly different crash traces).
