- Summary
- CVE-2026-64388 affecting package kernel 6.6.150.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
smb/client: fix chown/chgrp with SMB3 POSIX Extensions
Ownership (chown) and group (chgrp) modifications were being ignored when mounting with SMB3 POSIX Extensions unless CIFSMOUNTCIFSACL or CIFSMOUNTMODEFROM_SID were also explicitly set.
Fix this by checking for posixextensions in cifssetattrnounix() when updating UID and GID, ensuring that idmodetocifs_acl() is called to map and set the ownership/group information on the server.
