This page covers CVE-2026-41568 as tracked by Debian, for the package docker.io. The fix is available in version 28.5.2+dfsg4-3; earlier versions remain affected.
How this vulnerability can be exploited
This issue can be reached with local access to the system, attack complexity is high, an attacker needs low-level privileges on the target. A user must be tricked into taking some action. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality none, integrity low, availability high.
CVSS metrics in full
The score comes from this vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:N/I:L/A:H
- Attack vector: Local — a local account, shell or session on the host is needed.
- Attack complexity: High — the attacker first has to win a race, learn a secret or otherwise prepare the target.
- Privileges required: Low — an ordinary user account is enough.
- User interaction: Required — someone has to click, open or visit something.
- Scope: Changed — a successful attack reaches components beyond the vulnerable one.
- Confidentiality impact: None.
- Integrity impact: Low — limited, and the attacker does not choose what is affected.
- Availability impact: High — total loss, or loss the attacker controls.
