CVE-2026-13199: Insufficient Entropy in Raspberry Pi 5 and Compute Module 5

• Severity: medium (CVSS 4.0 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.2% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-07-07 · updated 2026-10-25
• Weakness: CWE-331

Description

EEPROM firmware on Raspberry Pi 5 and Compute Module 5 devices produced non-random KASLR and RNG seed values. This resulted in consistent kernel addresses across boots and devices, potentially making it easier to exploit other vulnerabilities. Additionally, the low-quality RNG seed may affect the quality of random numbers or delay booting while sufficient entropy is accumulated from other sources.

Affected products

• Raspberry Pi 5 and Compute Module 5: before 28.22-1 — fixed in 28.22-1

How to fix

Upgrade to a fixed version: Raspberry Pi 5 and Compute Module 5 28.22-1. Check the vendor advisory for mitigations.
