Integer overflow in the btrfs_ioctl_clone function in fs/btrfs/ioctl.c in the Linux kernel before 2.6.35 might allow local users to obtain sensitive information via a BTRFS_IOC_CLONE_RANGE ioctl call.

Security readout for executives and security teams

This is an old Linux kernel Btrfs flaw. A person who already has local access to an affected system might be able to read sensitive information because of an integer overflow in a Btrfs clone-range ioctl path. Likely exposure is limited to Linux systems running kernels before 2.6.35 where Btrfs is present and local users can access relevant filesystems. Internet-facing exposure is not indicated by the supplied sources. Treat this as a legacy Linux exposure issue. It is not shown as actively exploited, but it matters on old multi-user systems because local users may gain access to sensitive information. Mitigation focus: Upgrade affected Linux kernels to vendor-fixed packages or kernel 2.6.35 or later.; Review Ubuntu, SUSE, Red Hat, and upstream kernel guidance for applicable fixes.; Prioritize multi-user systems where untrusted local users can access Btrfs filesystems..
