CVE-2022-41860: Freeradius

High severity, CVSS 7.5. EPSS: 1.2% chance of exploitation in the next 30 days.

In freeradius, when an EAP-SIM supplicant sends an unknown SIM option, the server will try to look that option up in the internal dictionaries. This lookup will fail, but the SIM code will not check for that failure. Instead, it will dereference a NULL pointer, and cause the server to crash.

Affected products

• Freeradius Freeradius: from 0.9.3, up to and including 3.0.25
