CVE-2025-22080

Kernel compromise via wrapped NTFS index offset

Published Apr 16, 2025 · Updated Aug 5, 2026

Integer overflow in the Linux NTFS3 driver allows local users to compromise or crash 32-bit kernels via crafted NTFS media. On 32-bit builds, hdr_first_de adds sizeof(struct NTFS_DE) to attacker-controlled de_off without overflow-safe arithmetic, allowing the bounds check to accept a wrapped value. A local user must supply and cause the kernel to parse a malformed NTFS index; the resulting out-of-bounds access can corrupt kernel memory or stop the system.
