## What is CVE-2022-23960?

CVE-2022-23960 is a medium-severity vulnerability in Debian Debian Linux, published on 12 Mar 2022. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive information.

## Which versions are affected by CVE-2022-23960?

It affects 22 products.


Products: Arm Cortex-A57 Firmware, Arm Cortex-A65 Firmware, Arm Cortex-A65ae Firmware, Arm Cortex-A710 Firmware, Arm Cortex-A72 Firmware, Arm Cortex-A73 Firmware, Arm Cortex-A75 Firmware, Arm Cortex-A76 Firmware, Arm Cortex-A76ae Firmware, Arm Cortex-A77 Firmware, Arm Cortex-A78 Firmware, Arm Cortex-A78ae Firmware, Arm Cortex-R7 Firmware, Arm Cortex-R8 Firmware, Arm Cortex-X1 Firmware, Arm Cortex-X2 Firmware, Arm Neoverse-E1 Firmware, Arm Neoverse-V1 Firmware, Arm Neoverse N1 Firmware, Arm Neoverse N2 Firmware and 2 more.

Check this codebase for CVE-2022-23960 and fix it if it is affected.

What it is: CVE-2022-23960 is a medium-severity vulnerability in Debian Debian Linux, published on 12 Mar 2022. 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-2022-23960 in the wild and no public exploit code.

Affected product: Debian Debian Linux. 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.
