Vulnerability from github – Published: 2025-12-24 15:30 – Updated: 2025-12-24 15:30

Details

In the Linux kernel, the following vulnerability has been resolved:

iommufd: Set end correctly when doing batch carry

Even though the test suite covers this it somehow became obscured that this wasn't working.

The test iommufd_ioas.mock_domain.access_domain_destory would blow up rarely.

end should be set to 1 because this just pushed an item, the carry, to the pfns list.

Sometimes the test would blow up with:
