An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-50276 in the wild and no public exploit code.\n\nAffected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. 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.\n2. 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.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2024-50276/ (Markdown: https://insights.sbomify.com/CVE-2024-50276/index.md)","id":"CVE-2024-50276","markdown":"https://insights.sbomify.com/CVE-2024-50276/index.md","name":"CVE-2024-50276","record":{"aliases":["BELL-CVE-2024-50276","DEBIAN-CVE-2024-50276","GHSA-p9fm-3qq2-rmm2","UBUNTU-CVE-2024-50276"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A double free vulnerability in the Linux kernel's mse102x network driver can cause system crashes, requiring a kernel patch to resolve.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: vertexcom: mse102x: Fix possible double free of TX skb\n\nThe scope of the TX skb is wider than just mse102x_tx_frame_spi(),\nso in case the TX skb room needs to be expanded, we should free the\nthe temporary skb instead of the original skb.
