Ubuntu priority

Medium

Why this priority?

Off-by-one error in the iov_iter_advance function in mm/filemap.c in the Linux kernel before 2.6.27-rc2 allows local users to cause a denial of service (system crash) via a certain sequence of file I/O operations with readv and writev, as demonstrated by testcases/kernel/fs/ftest/ftest03 from the Linux Test Project.

From the Ubuntu Security Team

It was discovered that the readv/writev functions did not correctly handle certain sequences of file operations. A local attacker could exploit this to crash the system, leading to a denial of service.
