CVE-2011-4086
Last modified
CVE-2011-4086 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
