nfs2acl.c in the Linux kernel 2.6.14.4 does not check for MAY_SATTR privilege before setting access controls (ACL) on files on exported NFS filesystems, which allows remote attackers to bypass ACLs for readonly mounted NFS filesystems.

Security readout for executives and security teams

This flaw affects Linux kernel NFS ACL handling. A remote NFS client could set file ACLs without the expected permission check, bypassing controls on read-only mounted NFS exports. Business impact is unauthorized weakening or changing of file access controls on very old Linux NFS servers. The sources provide no CVSS score or active exploitation evidence. Exposure is most likely on legacy Linux systems running affected 2.6-era kernels as NFS servers with exported filesystems and ACL support enabled. Prioritize if the organization still runs legacy Linux NFS servers or inherited appliances. For modern patched fleets, urgency is lower, but legacy storage exposure should be verified because the issue affects access-control integrity. Mitigation focus: Review SUSE and Red Hat advisories for applicable kernel update packages.; Patch or retire affected 2.6-era Linux NFS servers.; Restrict NFS exports to trusted networks and hosts..
