CVE-2011-4086

Linux Kernel < 3.3.1 - Denial of Service via Journal Buffer Head State Mismanagement

Title source: llm
STIX 2.1

Description

The journal_unmap_buffer function in fs/jbd2/transaction.c in the Linux kernel before 3.3.1 does not properly handle the _Delay and _Unwritten buffer head states, which allows local users to cause a denial of service (system crash) by leveraging the presence of an ext4 filesystem that was mounted with a journal.
