• I reviewed the Contributing Guide.

Is your feature request related to a problem? Please describe.
Enabling address sanitizer can catch several memory issues in C programming.

Describe the solution you'd like
If possible i would like to see the address sanitizer added to the cfs pipeline CI pipeline.

Prior to make prep you would add the following exports.

export CFLAGS="-fsanitize=address -fno-omit-frame-pointer -g"
export CXXFLAGS="-fsanitize=address -fno-omit-frame-pointer -g"
export LDFLAGS="-fsanitize=address"

I belive you would make these changes to these two CI Workflows.

Modify Memory Handling in EVS

// In EVS module source file
#include <string.h>

void EVS_SendEvent(uint32 EventID, uint16 EventType, const char *Spec, ...)
{
if (Spec == NULL)
{
CFE_EVS_SendEvent(EventID, EventType, "Invalid format string");
return;
}
// Existing code to handle event
}

2. Explanation

What this does: Adds a null check for the format string (Spec) before proceeding with event handling.

Why this fixes it: Prevents segmentation faults caused by dereferencing null pointers.

Next steps: Implement similar null checks in other parts of the EVS module.

3. Git Commands

git checkout -b fix/evs-segmentation-fault

Modify EVS source file as described above

git add path/to/evs/source/file
git commit -m "Fix segmentation fault in EVS module by adding null check"
git push origin fix/evs-segmentation-fault
