TIMELINE Apr 16 Reserved by Linux Sep 4 Published (CNA: Linux) Jul 30 RESCORED — CVE-2025-38688 (Linux). CVSS 8.8 → 7.8 (NVD).
In the Linux kernel, the following vulnerability has been resolved: iommufd: Prevent ALIGN() overflow When allocating IOVA the candidate range gets aligned to the target alignment. If the range is close to ULONG_MAX then the ALIGN() can wrap resulting in a corrupted iova. Open code the ALIGN() using get_add_overflow() to prevent this. This simplifies the checks as we don't need to check for length earlier either. Consolidate the two copies of this code under a single helper. This bug would allow userspace to create a mapping that overlaps with some other mapping or a reserved range.
