## Description

Integer overflow in the ext4_ext_get_blocks function in fs/ext4/extents.c in the Linux kernel before 2.6.34 allows local users to cause a denial of service (BUG and system crash) via a write operation on the last block of a large file, followed by a sync operation.

## What to do

- Check your stack: if you ship or depend on n/a, no fixed version is listed yet; follow the vendor advisory per the references below.
