HIGHCVSS 7.1/10EPSS 0.24%

Last modified

CVE-2025-5090 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. CVX is not resilient to unexpected messages from a connected switch. This leads to agent crashes on CVX causing instability in the CVX cluster. EPSS estimates a 0.24% chance of exploitation in the next 30 days.

Description

CVX is not resilient to unexpected messages from a connected switch. This leads to agent crashes on CVX causing instability in the CVX cluster. An attacker could use this behavior to create a denial of service (DoS) scenario. Note that this would require the attacker to have a high privilege access to the connected switch to be able to send custom TCP packets to the CVX.
