The noncompliant example produces the following (unexpected) output.
| Code Block |
|---|
memory aligned to 4096 bytes ptr[0] (0x2b7000000000) : 0xb43c000 = 12.500000 ptr[1] (0x2b7000000004) : 0xb43c004 = 25.500000 After realloc(): ptr1[0] (0x2b7000000000) : 0xb43c000 = 12.500000 ptr1[1] (0x2b7000000008) = 0.000000 : 0xb43c008 = 0.000000 The value at ptr[1] remains the same after realloc() ptr[1] : 0xb43c004 = 25.500000 |
Risk Assessment
Improper alignment could lead to accessing arbitrary memory locations and write into it.
