## What is CVE-2024-11616?

CVE-2024-11616 is a medium-severity memory corruption vulnerability in Netskope Inc. Endpoint DLP, published on 19 Dec 2024. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Netskope was made aware of a security vulnerability in Netskope Endpoint DLP’s Content Control Driver where a double-fetch issue leads to heap overflow. The vulnerability arises from the fact that the NumberOfBytes argument to ExAllocatePoolWithTag, and the Length argument for RtlCopyMemory, both independently dereference their value from the user supplied input buffer inside the EpdlpSetUsbAction function, known as a double-fetch. If this length value grows to a higher value in between these two calls, it will result in the RtlCopyMemory call copying user-supplied memory contents outside the range of the allocated buffer, resulting in a heap overflow. A malicious attacker will need admin privileges to exploit the issue.
This issue affects Endpoint DLP version below R119.

Weakness: CWE-125 (Out-of-bounds Read)

Check this codebase for CVE-2024-11616 and fix it if it is affected.

What it is: CVE-2024-11616 is a medium-severity memory corruption vulnerability in Netskope Inc. Endpoint DLP, published on 19 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-2024-11616 in the wild and no public exploit code.

Affected product: Netskope Inc. Endpoint DLP. 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.
