GHSA-3v99-hpv7-9hh9

HIGH

GHSA-3v99-hpv7-9hh9 is a high-severity (CVSS 8.8) CWE-190 vulnerability in capstone. O3 Security confirms whether GHSA-3v99-hpv7-9hh9 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description

Integer overflow in the cs_winkernel_malloc function in winkernel_mm.c in Capstone 3.0.4 and earlier allows attackers to cause a denial of service (heap-based buffer overflow in a kernel driver) or possibly have unspecified other impact via a large value.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for capstone. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update capstone to 3.0.5rc2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3v99-hpv7-9hh9 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-3v99-hpv7-9hh9 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-3v99-hpv7-9hh9. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
