Last year, developers of the static code analyzer PVS-Studio already cited the result of their research on the operating system Tizen example and now again the choice fell on another, no less popular OS, Android. Looking ahead, I want to note that I didn't expect such a huge number of mistakes in such a popular product!

In the article, mistakes carried in even such a high-quality codeare striped on examples, in fact even those tested by ********.

In total, the developers described about 490 potential vulnerabilities. For example, CWE-14: Compiler Removal of Code to Clear Buffers, which is a serious type of potential vulnerability and leads to access to private data.

Among the others you can find:
CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer
CWE-393: Return of Wrong Status Code
CWE-480: Use of Incorrect Operator
CWE-561: Dead Code
CWE-690: Unchecked Return Value to NULL Pointer Dereference
CWE-762: Mismatched Memory Management Routines

And many other interesting examples of almost 2 million lines of code in C and C ++! Wow!
