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

Description The Linux kernel contains an issue within the ksmbd component related to the handling of FS OBJECT ID INFORMATION. The resolution involves utilizing the superblock's UUID (sb->s uuid) as the primary volume identifier. If a filesystem does not provide a UUID, the system falls back to using the filesystem ID (stfs.f fsid) obtained from vfs statfs().

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