Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An integer overflow occurs in the JFS file system within the jfs rename() function. When the nlink (number of hard links) for a directory is at its maximum value (-1) and a rename operation is performed on a child directory without moving it from the parent, the nlink of the parent directory is incremented and subsequently decremented. This sequence causes the value to wrap around to 0, leading the drop nlink() function to issue a warning.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
