# CVE-2024-53241: x86/xen: don't do PV iret hypercall through hypercall page

> A flaw in the Linux kernel's Xen PV implementation allowed bypassing speculation mitigations via hypercall page usage, requiring a patch to enforce direct assembly sequences.

- **Severity:** Medium 5.5 (`CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N`)
- **Exploited in the wild:** Not known
- **Login needed:** Any signed-in user
- **Attackable:** Local or same network only
- **Victim action needed:** Not needed
- **Fix available:** Yes
- **Published:** 24 Dec 2024
- **Updated:** 11 May 2026
- **Also known as:** BELL-CVE-2024-53241, DEBIAN-CVE-2024-53241, GHSA-w2vx-fp9q-36ph, ROOT-OS-UBUNTU-2204-CVE-2024-53241, SUSE-SU-2025:0142-1, UBUNTU-CVE-2024-53241

## What is CVE-2024-53241?

CVE-2024-53241 is a medium-severity vulnerability in Linux kernel, published on 24 Dec 2024. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

In the Linux kernel, the following vulnerability has been resolved:

x86/xen: don't do PV iret hypercall through hypercall page

Instead of jumping to the Xen hypercall page for doing the iret
hypercall, directly code the required sequence in xen-asm.S.

This is done in preparation of no longer using hypercall page at all,
as it has shown to cause problems with speculation mitigations.

This is part of XSA-466 / CVE-2024-53241.

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-53241 and fix it if it is affected.

What it is: CVE-2024-53241 is a medium-severity vulnerability in Linux kernel, published on 24 Dec 2024. 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-2024-53241 in the wild and no public exploit code.

Affected product: Linux kernel. 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.
