CVE-2026-47753

MEDIUMPre-NVD 4.44.4—
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 4.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 96% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Incus is a system container and virtual machine manager. Prior to version 7.1.0, (*backend).CreateInstanceFromBackup in internal/server/storage/backend.go contains a nil-pointer dereference that an authenticated user with permission to create instances in any project can trigger remotely by uploading a crafted backup tarball. The Incus daemon panics and the process crashes, causing denial of service to every project on that cluster member. This is a sibling of GHSA-fwj8-62r8-8p8m, GHSA-r7w7-mmxr-47r9, and GHSA-x5r6-jr56-89pv (all assigned 2026-05-04). Those patches added guards on adjacent fields of the same backup/config.Config struct; the Volume field on the instance-import path was missed. Version 7.1.0 contains an updated patch.
