| Security Vulnerability Related |
| ****************************** |
| |
| * A suitably sized k_malloc() request can result in a smaller than |
| requested buffer. Use of that buffer could result in writes to |
| unallocated memory. Proper overflow checks were added to fix this |
| issue in k_malloc and k_calloc. |
| |
| * kernel: mempool: Check for overflow in k_malloc() |
| * kernel: mempool: Always check for overflow in k_calloc() |
| * tests: mempool: Add overflow checks |
