CVE-2014-9710: The Btrfs implementation in the Linux kernel before 3.19 does not ensure that the visible xattr state is co...

Security readout for executives and security teams

This is a local Linux privilege-risk issue in Btrfs. On kernels before 3.19, replacing file extended attributes could briefly or persistently expose inconsistent ACL state, letting a local user bypass intended permissions. The source bundle does not show active exploitation or a CVSS score. Exposure is most likely on Linux systems using writable Btrfs filesystems with kernels before 3.19, unless vendor patches were backported. Systems without Btrfs use, without local untrusted users, or with patched vendor kernels have lower practical exposure. Treat as a targeted patching priority for older Linux/Btrfs hosts, especially shared servers. It is not described as remotely exploitable, but local privilege escalation can materially increase impact after an initial foothold. Mitigation focus: Apply the fixed upstream kernel or relevant vendor security update.; Confirm whether your distribution backported the CVE-2014-9710 fix.; Prioritize systems using Btrfs with local untrusted users or workloads..
