An issue in versions prior to 6.0.6 and 6.19.0 affects any Incus user in an environment where an unprivileged user may have root access to a container with an attached custom storage volume that has the `security.shifted` property set to `true` as well as access to the host as an unprivileged user. The most common case for this would be systems using `incus-user` with the less privileged `incus` group to provide unprivileged users with an isolated restricted access to Incus. Such users may be able to create a custom storage volume with the necessary property (depending on kernel and filesystem support) and can then write a setuid binary from within the container which can be executed as an unprivileged user on the host to gain root privileges. A patch for this issue is expected in versions 6.0.6 and 6.19.0. As a workaround, permissions can be manually restricted until a patched version of Incus is deployed.&#8221;,&#8221;published&#8221;:&#8221;2025-11-10T21:56:26.578Z&#8221;,&#8221;modified&#8221;:&#8221;2025-11-10T21:56:26.578Z&#8221;,&#8221;type&#8221;:&#8221;cve&#8221;,&#8221;title&#8221;:&#8221;Incus vulnerable to local privilege escalation through custom storage volumes&#8221;,&#8221;source&#8221;:&#8221;GitHub_M&#8221;,&#8221;references&#8221;:&#8221;https:\/\/github.com\/lxc\/incus\/security\/advisories\/GHSA-56mx-8g9f-5crf\\nhttps:\/\/github.com\/lxc\/incus\/issues\/2641\\nhttps:\/\/github.com\/lxc\/incus\/pull\/2642&#8243;,&#8221;id&#8221;:&#8221;CVE-2025-64507&#8243;,&#8221;bulletinFamily&#8221;:&#8221;&#8221;,&#8221;cwe&#8221;:[&#8220;CWE-269&#8243;],&#8221;cvelist&#8221;:null,&#8221;sourceData&#8221;:&#8221;lxc incus \\u003c 6.0.6\\nlxc incus \\u003e= 6.1.0, \\u003c 6.19.0&#8243;,&#8221;sourceHref&#8221;:&#8221;&#8221;,&#8221;cvss&#8221;:{&#8220;score&#8221;:8.6,&#8221;severity&#8221;:&#8221;HIGH&#8221;,&#8221;vector&#8221;:&#8221;CVSS:4.0\/AV:L\/AC:L\/AT:N\/PR:N\/UI:N\/VC:H\/VI:H\/VA:H\/SC:N\/SI:N\/SA:N&#8221;,&#8221;version&#8221;:&#8221;4.0&#8243;},&#8221;cvss2&#8243;:{},&#8221;cvss3&#8243;:{&#8220;version&#8221;:&#8221;&#8221;,&#8221;vectorString&#8221;:&#8221;&#8221;,&#8221;baseScore&#8221;:0,&#8221;baseSeverity&#8221;:&#8221;&#8221;,&#8221;attackVector&#8221;:&#8221;&#8221;,&#8221;attackComplexity&#8221;:&#8221;&#8221;,&#8221;privilegesRequired&#8221;:&#8221;&#8221;,&#8221;userInteraction&#8221;:&#8221;&#8221;,&#8221;scope&#8221;:&#8221;&#8221;,&#8221;confidentialityImpact&#8221;:&#8221;&#8221;,&#8221;integrityImpact&#8221;:&#8221;&#8221;,&#8221;availabilityImpact&#8221;:&#8221;&#8221;,&#8221;cvssV3&#8243;:{&#8220;version&#8221;:&#8221;&#8221;,&#8221;vectorString&#8221;:&#8221;&#8221;,&#8221;baseScore&#8221;:0,&#8221;baseSeverity&#8221;:&#8221;&#8221;,&#8221;attackVector&#8221;:&#8221;&#8221;,&#8221;attackComplexity&#8221;:&#8221;&#8221;,&#8221;privilegesRequired&#8221;:&#8221;&#8221;,&#8221;userInteraction&#8221;:&#8221;&#8221;,&#8221;scope&#8221;:&#8221;&#8221;,&#8221;confidentialityImpact&#8221;:&#8221;&#8221;,&#8221;integrityImpact&#8221;:&#8221;&#8221;,&#8221;availabilityImpact&#8221;:&#8221;&#8221;}},&#8221;href&#8221;:&#8221;&#8221;,&#8221;category_name&#8221;:&#8221;CVE&#8221;,&#8221;post_link&#8221;:&#8221;&#8221;,&#8221;product&#8221;:&#8221;incus&#8221;,&#8221;version&#8221;:&#8221;\\u003c 6.0.6&#8243;,&#8221;vendor&#8221;:&#8221;lxc&#8221;,&#8221;ai_description&#8221;:&#8221;Local privilege escalation vulnerability through custom storage volumes&#8221;,&#8221;ai_severity&#8221;:&#8221;High&#8221;,&#8221;ai_vendor&#8221;:&#8221;LXC&#8221;,&#8221;ai_product&#8221;:&#8221;Incus&#8221;,&#8221;ai_version&#8221;:&#8221;\\u003c 6.0.6, \\u003c 6.19.0&#8243;,&#8221;ai_score&#8221;:8.6}<\/p>\n","protected":false},"excerpt":{"rendered":"<p>{&#8220;lastseen&#8221;:&#8221;&#8221;,&#8221;description&#8221;:&#8221;Incus is a system container and virtual machine manager.
