CVE-2025-21667 Information

Description

In the Linux kernel the following vulnerability has been resolved:

iomap: avoid avoid truncating 64-bit offset to 32 bits

on 32-bit kernels iomap_write_delalloc_scan() was inadvertently using a 32-bit position due to folio_next_index() returning an unsigned long. This could lead to an infinite loop when writing to an xfs filesystem.
