Wildcard Attack Tests +- **Test**: `test_kernels_remove_wildcard_attack` +- **Attack Vector**: Using `*` in kernel name or version +- **Example**: `icrn_manager kernels remove R "malicious*" "1.0"` +- **Expected**: Rejection with "Invalid characters" error +- **Protection**: Regex validation prevents shell glob expansion + +### 2.
