How to fix?

Upgrade SLES:15.1 python2-protobuf to version 3.9.2-150100.8.3.3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python2-protobuf package and not the python2-protobuf package as distributed by SLES. See How to fix? for SLES:15.1 relevant fixed versions and status.

Nullptr dereference when a null char is present in a proto symbol. The symbol is parsed incorrectly, leading to an unchecked call into the proto file's name during generation of the resulting error message. Since the symbol is incorrectly parsed, the file is nullptr. We recommend upgrading to version 3.15.0 or greater.
