ETK-2026-3036Zero's internal tracking ID, independent of the CVE number.
waiting for further signalsZero needs more public information before it can validate it.description
Incusd versions 7.3.0 through v7.5.x can incorrectly associate a guest API request with another container on the same host. A process in one container may impersonate another container to read guest API-exposed configuration and device information or perform permitted guest API actions; image export risk requires guest image access to be enabled.
mitigation
Upgrade github.com/lxc/incus/v7/cmd/incusd to >= v7.6.0 or later.
fixed in >= v7.6.0
outcome
Contextual, not validated: no deterministic check could cover this one, and no technique passed our review.
