🛡️ CVE-2025-22840

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 high, integrity high, availability low.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:L

• 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: High — total loss, or loss the attacker controls.
• Integrity impact: High — total loss, or loss the attacker controls.
• Availability impact: Low — limited, and the attacker does not choose what is affected.
