CVE-2025-22080 Information

Description

In the Linux kernel the following vulnerability has been resolved:

fs/ntfs3: Prevent integer overflow in hdr_first_de()

The \de_off\ and �sed\ variables come from the disk so they both need to check. The problem is that on 32bit systems if they’re both greater than UINT_MAX - 16 then the check does work as intended because of an integer overflow.
