# CVE-2023-3090: Out-of-bounds write in Linux kernel's ipvlan network driver > A heap out-of-bounds write in the Linux kernel ipvlan driver allows local attackers to escalate privileges when the feature is enabled. - **Severity:** High 7.8 (`CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H`) - **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:** 28 Jun 2023 - **Updated:** 5 Mar 2025 - **Also known as:** AZL-27350, DEBIAN-CVE-2023-3090, GHSA-295v-9m5g-79q9, RHSA-2023:4828, UBUNTU-CVE-2023-3090 ## What is CVE-2023-3090? CVE-2023-3090 is a high-severity memory corruption vulnerability in Debian Debian Linux, published on 28 Jun 2023. It can only be exploited from the same machine or local network, with no action from the victim. ### Official description A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to achieve local privilege escalation. The out-of-bounds write is caused by missing skb->cb initialization in the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled. We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e. Weakness: CWE-787 (Out-of-bounds Write) ## Which versions are affected by CVE-2023-3090?

What it is: CVE-2023-3090 is a high-severity memory corruption vulnerability in Debian Debian Linux, published on 28 Jun 2023. It can only be exploited from the same machine or local network, with no action from the victim. Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-3090 exists. 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.
