Risk Assessment Summary
Rule | Severity | Likelihood | Detectable | Repairable | Priority | Level |
|---|---|---|---|---|---|---|
| MEM30-C | High | Likely | No | No | P9 | L2 |
| MEM31-C | Medium | Probable | No | No | P4 | L3 |
| MEM33-C | Low | Unlikely | Yes | No | P2 | L3 |
| MEM34-C | High | Likely | No | No | P9 | L2 |

Recommendations
MEM00-C. Allocate and free memory in the same module, at the same level of abstraction
MEM01-C. Store a new value in pointers immediately after free()
MEM03-C. Clear sensitive information stored in reusable resources returned for reuse
MEM04-C. Do not perform zero length allocations
MEM05-C. Avoid large stack allocations
MEM06-C. Ensure that sensitive data is not written out to disk
MEM07-C. Ensure that the arguments to calloc(), when multiplied, can be represented as a size_t
MEM08-C. Use realloc() only to resize dynamically allocated arrays
MEM09-C. Do not assume memory allocation routines initialize memory
MEM10-C. Define and use a pointer validation function
MEM11-C. Do not assume infinite heap space
MEM12-C. Use a Goto-Chain when leaving a function on error after allocating multiple objects
Rules
MEM30-C. Do not access freed memory
MEM31-C. Free dynamically allocated memory exactly once
MEM32-C. Detect and handle memory allocation errors
MEM33-C. Use the correct syntax for flexible array members
MEM34-C. Only free memory allocated dynamically
MEM35-C. Allocate sufficient memory for an object
MEM36-C. Check for alignment of memory space before calling realloc()function
