CVE-2026-82480 High · 7.4 CWE-189 Aug 30, 2026

NASA cFS cFE Software Bus cfe_sb_util.c CFE_SB_GetUserDataLength integer underflow

A security flaw has been discovered in NASA cFS up to 7.0.1. The affected element is the function CFE_SB_GetUserDataLength of the file src/cFS/cfe/modules/sb/fsw/src/cfe_sb_util.c of the component cFE Software Bus. Performing a manipulation of the argument TotalMsgSize/HdrSize results in integer underflow. It is possible to initiate the attack remotely. The vendor was contacted early about this disclosure but did not respond in any way.

CVE-2026-82479 Medium · 6.3 CWE-119 Aug 30, 2026

NASA cFS SBN TCP sbn_tcp_if.c OS_read buffer overflow

A vulnerability was identified in NASA cFS up to 7.0.1. Impacted is the function OS_read of the file modules/protocol/tcp/fsw/src/sbn_tcp_if.c of the component SBN TCP Module. Such manipulation of the argument MsgSz leads to buffer overflow. The attack must be carried out from within the local network. The vendor was contacted early about this disclosure but did not respond in any way.

CVE-2026-5476 Medium · 4.6 CWE-189 Apr 3, 2026

NASA cFS cfe_tbl_passthru_codec.c CFE_TBL_ValidateCodecLoadSize integer overflow

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.

CVE-2026-5475 Medium · 5.5 CWE-119 Apr 3, 2026
