CVE-2023-20702
Estado: ModificadaAlta (7.5)—
In 5G NRLC, there is a possible invalid memory access due to lack of error handling. This could lead to remote denial of service, if UE received invalid 1-byte rlc sdu, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY00921261; Issue ID: MOLY01128895.
