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

Description A flaw exists in the Linux kernel related to the handling of sb->s fs info within the HFS filesystem code. A memory leak could occur during the superblock allocation process when transitioning to the new mount API. Specifically, if setup bdev super() fails after a new superblock is allocated by sget fc(), but before hfs fill super() takes ownership of the filesystem-specific s fs info data, the memory associated with sb->s fs info was not properly freed. The issue is addressed by freeing sb->s fs info in the hfs kill super() function.

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