How to fix?

Upgrade SLES:15.1 freeradius-server-mysql to version 3.0.16-150000.3.13.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream freeradius-server-mysql package and not the freeradius-server-mysql package as distributed by SLES. See How to fix? for SLES:15.1 relevant fixed versions and status.

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.
