CVE-2026-31410 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ksmbd: use volume UUID in FS_OBJECT_ID_INFORMATION Use sb->s_uuid for a proper volume identifier as the primary choice. For filesystems that do not provide a UUID, fall back to stfs.f_fsid obtained from vfs_statfs().
A vulnerability in the Linux kernel's ksmbd component relates to how volume UUIDs are managed in FS_OBJECT_ID_INFORMATION. The issue has been addressed by prioritizing the use of the filesystem's UUID as the main volume identifier. For filesystems lacking a UUID, the identifier will default to the filesystem ID obtained from vfs_statfs().
Users can update to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for updating the Linux kernel can be found in the official Linux documentation.
