# CVE-2015-3331: Memory corruption in n/a > A buffer overflow in the Linux kernel's AES-NI crypto driver allows local attackers to cause a system crash or execute arbitrary code. - **Severity:** Critical 9.3 (`AV:N/AC:M/Au:N/C:C/I:C/A:C`) - **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:** 27 May 2015 - **Updated:** 6 Aug 2024 - **Also known as:** DEBIAN-CVE-2015-3331, GHSA-px59-358h-xw3q, RHSA-2015:0981, RHSA-2015:0987, RHSA-2015:0989, UBUNTU-CVE-2015-3331 ## What is CVE-2015-3331? CVE-2015-3331 is a critical memory corruption vulnerability in Canonical Ubuntu Linux, published on 27 May 2015. It can only be exploited from the same machine or local network, with no action from the victim. ### Official description The __driver_rfc4106_decrypt function in arch/x86/crypto/aesni-intel_glue.c in the Linux kernel before 3.19.3 does not properly determine the memory locations used for encrypted data, which allows context-dependent attackers to cause a denial of service (buffer overflow and system crash) or possibly execute arbitrary code by triggering a crypto API call, as demonstrated by use of a libkcapi test program with an AF_ALG(aead) socket. Weakness: CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) ## Which versions are affected by CVE-2015-3331?

What it is: CVE-2015-3331 is a critical memory corruption vulnerability in Canonical Ubuntu Linux, published on 27 May 2015. 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-2015-3331 in the wild and no public exploit code. Affected product: Canonical Ubuntu 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.
