Low (2.1) in nasa core flight system. EPSS 0.2% chance of exploitation in the next 30 days.
A vulnerability was identified in NASA cFS up to 7.0.0 on 32-bit. Affected is the function CFE_TBL_ValidateCodecLoadSize of the file cfe/modules/tbl/fsw/src/cfe_tbl_passthru_codec.c. The manipulation leads to integer overflow. The complexity of an attack is rather high. The exploitability is told to be difficult. A fix is planned for the upcoming version milestone of the project.
