Hello, When using Healer to fuzz the Linux-6.6-rc3, the following crash was triggered. HEAD commit: 6465e260f48790807eef06b583b38ca9789b6072 ( Linux 6.6-rc3） git tree: upstream console output: https://drive.google.com/file/d/1buerWpksX6CT-OKEQR74FqOO0YffAqtg/view?usp=drive_link kernel config:https://drive.google.com/file/d/19l-irNJwbbXbjirevwkZpA67Wfw5DyOr/view?usp=drive_link C reproducer:https://drive.google.com/file/d/1KDia7KFRB8cAuSikuZ2UCtWvpW69vbmJ/view?usp=drive_link Syzlang reproducer: https://drive.google.com/file/d/11Pbt5sdyZrqlMg35Go1dlH8IVBQjRKAI/view?usp=drive_link My local Linux repository is a few commits behind the main branch, so I pulled the latest branch and validated the crash on it. The issue still persists.
