Summary
CodeQL identified two go/allocation-size-overflow findings (warning severity): #661 in pkg/workflow/tools.go and #660 in pkg/cli/experiments_analyze_statistics.go. Both flag potential integer overflow feeding an allocation size, which can lead to unexpected allocation sizes, panics, or resource-exhaustion (DoS) conditions if the size expression is derived from untrusted/large input.
Both files were recently touched as part of this week's value-grader / experiments-analysis feature work (#55155) and are not yet tracked by any existing governance issue.
Tier and risk-scoring breakdown
- Tier: B — Open With Conditions
- Exposure amplification: Low (requires attacker-controlled size input to reach the allocation)
- Patchability: High (bound/validate size expressions before allocation; add explicit overflow checks)
- Detectability: High (CodeQL already flags it in CI)
- Operational fragility: Low (worst case is a crash/panic, not code execution)
- Ownership confidence: Medium (recently changed files, active feature development)
Remediation action
Review the flagged allocation sites in pkg/workflow/tools.go and pkg/cli/experiments_analyze_statistics.go; add explicit bounds checking or safe-multiplication/overflow guards before using computed sizes in make()/allocation calls. Add unit test coverage for boundary/overflow inputs.
SLA urgency
High
