A flaw in the Linux Kernel found for the XFS file system. When mounting a user-supplied XFS disk image, the out of bounds memory access can happen. It happens for some corner case when data in Log journal of XFS image different from on-disk buffer that appears to be newer (so this is a dirty log case).
