### Patch 1: Input Validation
To fix the CWE-190 vulnerability, we can add input validation to ensure that `ticks_from_now` is within a valid range. This can be done by checking if `ticks_from_now` is less than or equal to a maximum allowed value.

```c
13     if (ticks_from_now > BLE_HS_MAX_TICKS) {
14         ticks_from_now = BLE_HS_MAX_TICKS;
15     }
16     abs_time = ble_npl_time_get() + ticks_from_now;
```

### Patch 2: Integer Overflow Check
Another way to fix the vulnerability is to check for integer overflow before performing the addition.

```c
13     if (ble_npl_time_get() > INT32_MAX - ticks_from_now) {
14         // Handle overflow error
15         return;
16     }
17     abs_time = ble_npl_time_get() + ticks_from_now;
```

### Patch 3: Use of Safe Arithmetic Functions
We can use safe arithmetic functions that check for overflow and underflow, such as `safe_add32` from the `safe_arith.h` library.

```c
13     if (!safe_add32(ble_npl_time_get(), ticks_from_now, &abs_time)) {
14         // Handle overflow error
15         return;
16     }
```

### Patch 4: Use of 64-bit Arithmetic
To avoid integer overflow, we can use 64-bit arithmetic to calculate `abs_time`.

```c
13     int64_t temp = (int64_t)ble_npl_time_get() + ticks_from_now;
14     if (temp > INT32_MAX || temp < INT32_MIN) {
15         // Handle overflow error
16         return;
17     }
18     abs_time = (int32_t)temp;
```

### Patch 5: Clamping the Result
We can clamp the result of the addition to a valid range to prevent overflow.

```c
13     abs_time = ble_npl_time_get() + ticks_from_now;
14     if (abs_time > INT32_MAX) {
15         abs_time = INT32_MAX;
16     } else if (abs_time < INT32_MIN) {
17         abs_time = INT32_MIN;
18     }
```

Note: The above patches are just examples and may need to be modified to fit the specific requirements of the code. Additionally, the `BLE_HS_MAX_TICKS` constant and the `safe_add32` function are not defined in the provided code and would need to be implemented separately.
