GHSA-gv7f-5qqh-vxfx
xous has unsound usages of `core::slice::from_raw_parts`
Blast Radius
xousReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.
Description
We consider as_slice and as_slice_mut unsound because: the pointer with any bit patterns could be cast to the slice of arbitrary types. The pointer could be created by unsafe new and deprecated from_parts. We consider that from_parts should be removed in latest version because it will help trigger unsoundness in as_slice. With new declared as unsafe, as_slice should also declared as unsafe.
This was patched in by marking two functions as unsafe.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for xous. 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.
Fix
Update xous to 0.9.51 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gv7f-5qqh-vxfx is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether GHSA-gv7f-5qqh-vxfx 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-gv7f-5qqh-vxfx. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-gv7f-5qqh-vxfx in your dependencies?
O3 detects GHSA-gv7f-5qqh-vxfx across crates.io dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
