Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A flaw exists in the gfs2 fiemap() function where iomap fiemap() is called while the inode glock (global lock) is held. This can result in recursive glock acquisition if the fiemap buffer is memory mapped to the same inode and accessing it triggers a page fault.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
