[Daniel Marjamäki](https://www.cppcheck.com/product-news/author/daniel-marjamäki) Oct 1, 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 26.9.0! **Cppcheck Premium 26.9.0** is now available. This release focuses on improving detection accuracy across **MISRA**, **CERT**, and **AUTOSAR** standards, with refined rule checks and better handling of a wide range of C and C++ code patterns. Numerous false positives and false negatives have been addressed, alongside improvements to existing CERT checks and MISRA rule reporting. Cppcheck Premium 26.9.0 is based on **Cppcheck 2.22.0**. See the [Cppcheck 2.22.0 release notes](https://github.com/cppcheck-opensource/cppcheck/releases/tag/2.22.0) for changes in the open source core. ## What’s New in 26.9.0 ### New features and improvements: • Added `` attribute for Misra C++ 2023 rules 0.1.2 (ADDON-736), 7.11.2 (ADDON-807), 8.2.2 (ADDON-739) and 8.2.6 (ADDON-740). • Misra C 10.4: added notes about literal suffixes (ADDON-729). • Misra C 11.4: better location when the cast is in an expanded macro (ADDON-800). • Fixed wrong warning id for Misra C++ 2023 directive 5.7.2 (ADDON-814). • Fixed wrong output for CERT MSC30-C (ADDON-767).   ## Improved checks: - **CERT MEM50-CPP:** allocating 0 bytes and dereferencing the pointer (ADDON-156). - **CERT MEM56-CPP:** shared\_ptr assigned the internal pointer of another shared\_ptr (ADDON-166). - **CERT MSC54-CPP:** exception handler with try/catch (ADDON-168). ## False negatives fixed: - **Misra C 2.2:** division by 1 (ADDON-776). - **Misra C 2.4:** tag in typedef only used implicitly (ADDON-487). - **Misra C 8.2:** void\* parameter (ADDON-808). - **Misra C 8.5:** declarations both in source and header (ADDON-454). - **Misra C 17.5:** argument pointer variable not checked (ADDON-616). - **Misra C 20.6**: #ifdef/#else/#endif directives inside macro arguments (ADDON-591). - **Misra C 21.14:** pointers to null-terminated strings produced by string functions (ADDON-697). - **Misra C++ 2023 7.0.5:** arithmetic between int and unsigned int (ADDON-809). - **Misra C++ 2023 8.1.1:** lambda in a regular function (ADDON-828). - **Misra C++ 2023 9.5.2:** implicit function call (ADDON-830). - **Misra C++ 2023 10.2.3:** non-variable enums (ADDON-831). - **Misra C++ 2023 21.6.2:** new in member initialization list (ADDON-833). - **Misra C++ 2023 21.10.1:** use of features from \ (ADDON-702). ## False positives fixed: • Misra C 5.6: typedef name matching its own associated tag (ADDON-771). • Misra C 8.2: named 'void \*' parameter (ADDON-727). • Misra C 8.18: initialized static object in header flagged as tentative definition (ADDON-751). • Misra C 10.3: removed positive-constexpr, there is an explicit exception (ADDON-743). • Misra C 11.1: cast of function-pointer parameter to void (ADDON-779). • Misra C 12.2: essential type computed as unsigned char instead of unsigned int (ADDON-799). • Misra C 14.2: write through dereferenced counter (ADDON-726), for loop initialization by function (ADDON-761), different structure member modified in loop body (ADDON-791). • Misra C 17.3: macro offsetof (ADDON-734), function declared only via --library (ADDON-763), function mentioned in posix.cfg (ADDON-781). • Misra C 17.8: ptr-\>a = 42 (ADDON-735). • Misra C 17.11: function is returning (ADDON-731), function call in while loop that modifies variable (ADDON-775), function call/post decrement in loop condition (ADDON-818). • Misra C 17.12: \_Generic (ADDON-842). • Misra C 21.2 / CERT DCL37-C: non-file-scope identifiers starting with underscore (ADDON-764). • Misra C Dir 4.10: #pragma once (ADDON-752). • misra-config: unknown function (ADDON-810), sizeof(struct S) (ADDON-844). • Misra C++ 2023 6.7.2: constexpr (ADDON-719). • Misra C++ 2023 7.0.5: uintN\_t + uint32\_t (ADDON-737). • Misra C++ 2023 8.2.2: function pointer initialization (ADDON-717). • Misra C++ 2023 8.2.5: exception for cast not applied (ADDON-741). • AUTOSAR A0-1-3: template specializations (ADDON-522). • AUTOSAR A5-2-2: (void) cast (ADDON-856), template arguments (ADDON-859). • CERT ERR33-C: return value explicitly cast to void (ADDON-698). • CERT EXP20-C: explicit equality comparison such as foo() == -1 (ADDON-732). • CERT EXP30-C: lambda call (ADDON-689). • CERT EXP34-C: overloaded arrow operator (ADDON-864). • CERT EXP36-C: target type is packed (alignment == 1) (ADDON-526). • CERT MSC40-C: does not apply to C++ (ADDON-843), const variable (ADDON-845). • CERT STR30-C: no string literal (ADDON-754). • CERT DCL56-CPP: incorrect "recursive initialization" warning (ADDON-648). --- ### Summary Cppcheck Premium 26.9.0 improves analysis accuracy across MISRA C, MISRA C++ 2023, CERT C/C++, and AUTOSAR rule sets. The release includes enhanced CERT checks, improved MISRA rule handling and reporting, and numerous fixes for false positives and false negatives across C and C++ analysis. ## Similar posts ![Cppcheck Premium](https://www.cppcheck.com/hubfs/Cppcheck%20Premium.png) Cppcheck Solutions AB S:t Göransgatan 95 112 45 Stockholm, Sweden    For sales inquires, please use the form above.   For legal, IR or supplier inquires, please contact us through: [par.jelger@cppcheck.com](mailto:par.jelger@cppcheck.com) ### More information - [About us](https://www.cppcheck.com/about) - [An introduction to static code analysis](https://www.cppcheck.com/what-is-static-code-analysis) - [EULA](https://www.cppcheck.com/eula) - [Privacy policy](https://www.cppcheck.com/privacy-policy) ### Help & Contact - [Known Issues](https://files.cppchecksolutions.com/known-issues-jira.html) - [Install & Register – Trial](https://www.cppcheck.com/cppcheck-premium-installation-trial) - [Install & Register – Individual License](https://www.cppcheck.com/cppcheck-premium-installation-individual) - [Install & Register – Enterprise License](https://www.cppcheck.com/cppcheck-premium-installation-enterprise) Copyright © 2026 Cppcheck Solutions AB.  VAT SE559293880601 Cookie Settings
