Distribution advisory
This page covers CVE-2023-0185 as tracked by Ubuntu, for the package nvidia-graphics-drivers-304. The fix is available in version 450.236.01-0ubuntu0.22.04.1; 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 administrative privileges on the target. No user interaction is required. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality low, integrity low, availability high.
CVSS metrics in full
The score comes from this vector: CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:L/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: High — administrative rights are needed first.
- User interaction: None — nobody has to be tricked into anything.
- Scope: Changed — a successful attack reaches components beyond the vulnerable one.
- Confidentiality impact: Low — limited, and the attacker does not choose what is affected.
- Integrity impact: Low — limited, and the attacker does not choose what is affected.
- Availability impact: High — total loss, or loss the attacker controls.
Weakness class
