[Daniel Marjamäki](https://www.cppcheck.com/product-news/author/daniel-marjamäki) Jan 12, 2026 [Software update](https://www.cppcheck.com/product-news/tag/software-update) [Cppcheck premium](https://www.cppcheck.com/product-news/tag/cppcheck-premium) ![](https://www.cppcheck.com/hubfs/Software%20Update%20Premium.png) Discover the updates in Cppcheck Premium version 26.1.0! Cppcheck Premium **26.1.0** is now available. This release focuses on improving accuracy and usability across **MISRA C/C++** and **CERT C/C++** compliance checking, with a strong emphasis on reducing false positives and improving rule coverage and reporting. ## What’s New in 26.1.0 ### MISRA C Enhancements #### MISRA C:2025 MISRA C:2025 support continues to mature in this release. The compliance report display for MISRA C:2025 rules has been corrected, ensuring clearer and more reliable reporting when working with the latest version of the standard. #### Expanded Rule Coverage and Accuracy Cppcheck Premium 26.1.0 includes a large number of targeted improvements across MISRA C rules, addressing both false positives and false negatives: - **Identifiers and linkage**: Improved handling of static, extern, and global identifiers, including better detection of name clashes and linkage inconsistencies (Rules 1.5, 5.1, 5.3, 5.7–5.9). - **Type conversions and expressions**: Enhanced checking for enum conversions, float-to-double conversions, implicit casts, and assignment correctness (Rules 10.1–10.6, 11.1, 11.5). - **Macros and preprocessing**: Reduced false positives related to `#define` / `#undef` usage and null pointer macros (Rules 2.5, 11.5). - **Control flow and side effects**: Improved detection of loop counter modification, volatile variable increments, and chained member access (Rules 13.2, 13.3, 14.2). - **Function usage**: Better handling of function pointers, extern variables, and functions defined in custom configuration files (Rules 8.2, 21.2). - Improved handling of struct member access patterns. - Improved essential type resolution for function return values These refinements improve confidence in MISRA compliance results, particularly for large or legacy codebases. MISRA C++ 2023 Improvements MISRA C++ analysis has also been refined in this release: - **Rule 7.0.3**: Improved distinction between `char` and `int8_t` / `uint8_t` types. - **Rule 9.4.2**: Improved detection of missing `default` cases in `switch` statements. These updates reduce unnecessary findings and improve correctness for modern C++ code. ### CERT C/C++ Secure Coding #### CERT C/C++ Security Enhancements Cppcheck Premium 26.1.0 strengthens CERT C/C++ coverage with both accuracy improvements and robustness fixes: - **ARR30-C**: Improved detection of unconditional pointer arithmetic (CVE-2018-14938). - **CTR50-CPP**: Fixed false positives in iterator and loop index handling. - **DCL06-C / DCL37-C**: Enhanced constant checking and better handling of custom configuration files. - **EXP34-C**: Fixed crashes and improved validation of custom library parameters. - **EXP50-CPP**: Improved detection of unknown evaluation order involving side effects. - **MEM52-CPP**: More accurate checking for `new` after allocation. These changes help teams identify real security risks while reducing noise in analysis results. ### Configuration and Reporting Improvements Several updates in this release improve usability and reporting clarity: - **Compliance reports** now return successful exit codes where appropriate and provide clearer suppression and coverage information. - Improved mapping for dangerous type casts in reports. - Better display of suppression comments. Together, these changes make compliance results easier to interpret and integrate into automated workflows. --- ### Summary Cppcheck Premium 26.1.0 focuses on incremental improvements to compliance checking, including more accurate MISRA C:2025 handling, expanded rule coverage, refinements to CERT checks, and clearer compliance reporting. ## Similar posts Software update ### [Cppcheck Premium 25.8.0 released – Full MISRA C:2025 Coverage](https://www.cppcheck.com/product-news/cppcheck-premium-25.8.0-released-full-misra-c2025-coverage) Cppcheck Premium 25.8.0 now supports all MISRA C:2025 guidelines, adds HIS Metrics, new CERT checks, and faster compliance analysis without misra.py.
