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

Description A regression was introduced in the SMB client that caused backup and copy tools to fail when encountering symlink targets that the client could not parse, even when those symlinks were not followed. The issue was resolved by allowing lstat(2) and readlink(2) to succeed even when the client cannot resolve the symlink target, restoring previous behavior.

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