CVE-2024-50272

Local file-read hang via offset overflow

Published Nov 19, 2024 · Updated May 23, 2026

Infinite loop in the Linux kernel allows local users to hang file reads by supplying an overflowing file offset and iterator count. filemap_read() adds the iterator count to iocb->ki_pos without correctly bounding overflow near the filesystem limit, so its read loop cannot terminate. Local low-privileged access is required; the consequence is an availability loss without reported data disclosure or modification.
