CVE-2026-115377Incus before 6.0.7, 6.1.0 before 7.0.2, and 7.1.0 before 7.5.0 contains an arbitrary file write vulnerability that allows malicious migration sources to write host files by...
Executive summaryA flaw in Incus, a system container and virtual machine manager, lets a malicious migration source or a client allowed to create instances write arbitrary files to the host as root, which can lead to full host compromise. The advisory rates it Critical with a CVSS 3.1 base score of 9.9. The fixed releases named are Incus 6.0.7, 7.0.2, and 7.5.0, depending on the branch. Technical summaryThe weakness is CWE-59, improper link resolution before file access, where symlinks in a migration stream are followed when Incus replays the stream with rsync or btrfs receive. Exploitation requires network-reachable access as a client allowed to create instances or custom volumes in a project, or a malicious source server the target copies or moves from, with low privileges and no user interaction. The advisory states that releases before 7.3.0 are additionally affected by a rootfs symlink surviving the transfer, which can allow host files to be read. Affected versions are listed as before 6.0.7, 6.1.0 before 7.0.2, and 7.1.0 before 7.5.0, and the GitHub package entry lists patched versions as 7.5.0 or later. The advisory does not state workarounds beyond restricting instance creation and migration to trusted clients and servers, and it does not state detection guidance or whether the flaw is exploited in the wild. Optimized ZFS transfers are stated to be unaffected. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
