## What is CVE-2025-68657?

CVE-2025-68657 is a medium-severity vulnerability in espressif esp-usb, published on 12 Jan 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Espressif ESP-IDF USB Host HID (Human Interface Device) Driver allows access to HID devices. Prior to 1.1.0, calls to hid_host_device_close() can free the same usb_transfer_t twice. The USB event callback and user code share the hid_iface_t state without locking, so both can tear down a READY interface simultaneously, corrupting heap metadata inside the ESP USB host stack. This vulnerability is fixed in 1.1.0.

Weakness: CWE-667 (Improper Locking), CWE-415 (Double Free)

What it is: CVE-2025-68657 is a medium-severity vulnerability in espressif esp-usb, published on 12 Jan 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-68657 in the wild and no public exploit code.

Affected product: espressif esp-usb. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
