Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw where a deadlock can occur when converting an inline directory in nojournal mode. Specifically, the
ext4 finish convert inline dir() function may cause a self-deadlock by calling ext4 handle dirty dirblock() while already holding the directory lock. A similar self-deadlock exists in ext4 incvert inline data nolock() for data files. The issue can be reproduced by creating an ext2 filesystem with inline data, mounting it as ext4 with dirsync enabled, creating a directory, and setting an extended attribute.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
