- Summary
- iomap: Fix possible overflow condition in iomap_write_delalloc_scan
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
iomap: Fix possible overflow condition in iomapwritedelalloc_scan
folionextindex() returns an unsigned long value which left shifted by PAGESHIFT could possibly cause an overflow on 32-bit system. Instead use foliopos(folio) + folio_size(folio), which does this correctly.
