## What is CVE-2024-24474?

CVE-2024-24474 is a high-severity vulnerability in Qemu Qemu, published on 20 Feb 2024. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

QEMU before 8.2.0 has an integer underflow, and resultant buffer overflow, via a TI command when an expected non-DMA transfer length is less than the length of the available FIFO data. This occurs in esp_do_nodma in hw/scsi/esp.c because of an underflow of async_len.

Weakness: CWE-191 (Integer Underflow (Wrap or Wraparound)), CWE-120 (Buffer Copy without Checking Size of Input)

Check this codebase for CVE-2024-24474 and fix it if it is affected.

What it is: CVE-2024-24474 is a high-severity vulnerability in Qemu Qemu, published on 20 Feb 2024. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-24474 exists.

Affected product: Qemu Qemu. 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.
5. If nothing in the project is affected, say so and change nothing.
