GHSA-gv7f-5qqh-vxfx — xous
Fix: betrusted-io/xous-core#411GHSA-gv7f-5qqh-vxfx is a security vulnerability in xous. A fix is available for xous — see the affected versions and patch details below.
xous has unsound usages of `core::slice::from_raw_parts`
Real-World Exposure
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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-gv7f-5qqh-vxfx can be triaged on real exposure rather than presence alone.
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 Security finds GHSA-gv7f-5qqh-vxfx across crates.io dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
