SCA: security update for github.com/lxc/incus/v7 (GHSA-8g7m-96c8-8wwc)

high Tenable Self-Hosted Container Security Plugin ID 443062

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-47753)

Solution

Update the github.com/lxc/incus/v7 library and its related packages to version 7.1.0 or later.
