CVE-2022-38773

4.6 MEDIUM 0.3% exploit odds Fix listed

What it is

Affected devices do not contain an Immutable Root of Trust in Hardware. With this the integrity of the code executed on the device can not be validated during load-time. An attacker with physical access to the device could use this to replace the boot image of the device and execute arbitrary code.

At a glance

Exploitability: Can be exploited with physical access without logging in. High risk of data tampering.
Exploit odds: 0.3% chance of exploitation in the next 30 days (EPSS).
Fix: A patch, advisory or fixed version is referenced. Upgrade or apply it.
