Linux Distros Unpatched Vulnerability : CVE-2025-21724

high Nessus Plugin ID 230695

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- 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. (CVE-2025-21724)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
