Description
An integer overflow vulnerability was found in the Linux kernel's IOMMUFD selftest infrastructure. The IOMMU_TEST_OP_ADD_RESERVED ioctl does not properly validate user-supplied length values, allowing arithmetic overflow that corrupts the reserved interval tree and triggers a WARN_ON. This issue only affects test kernels compiled with CONFIG_IOMMUFD_TEST enabled.
Mitigation
Minimal update. May introduce new vulnerabilities or breaking changes.
