CVE-2025-21724
Description
In the Linux kernel, the following vulnerability has been resolved:
iommufd/iova_bitmap: Fix shift-out-of-bounds in iova_bitmap_offset_to_index()
Resolve a UBSAN shift-out-of-bounds issue in iova_bitmap_offset_to_index() where shifting the constant "1" (of type int) by bitmap->mapped.pgshift (an unsigned long value) could result in undefined behavior.
The constant "1" defaults to a 32-bit "int", and when "pgshift" exceeds 31 (e.g., pgshift = 63) the shift operation overflows, as the result cannot be represented in a 32-bit type.
To resolve this, the constant is updated to "1UL", promoting it to an unsigned long type to match the operand's type.
