Vulnerability from fkie_nvd - Published: 2026-01-14 15:16 - Updated: 2026-03-25 18:36

Severity

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: iommufd/selftest: Check for overflow in IOMMU_TEST_OP_ADD_RESERVED syzkaller found it could overflow math in the test infrastructure and cause a WARN_ON by corrupting the reserved interval tree. This only effects test kernels with CONFIG_IOMMUFD_TEST. Validate the user input length in the test ioctl.
