CVE-2022-41860 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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. EPSS estimates a 1.17% chance of exploitation in the next 30 days.

Description
