Miggo AIRoot Cause Analysis

The vulnerability description explicitly identifies the 'relocate' function in src/elf.rs as containing the integer overflow. The code analysis shows sym.st_value is used in an unchecked addition operation. The GitHub advisory and CVE both confirm this is the vulnerable function. The fix in v0.2.17 adds overflow checks (e.g., checked_add), validating this as the root cause location.
