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-2022-49094 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-2022-49094/ (Markdown: https://insights.sbomify.com/CVE-2022-49094/index.md)","id":"CVE-2022-49094","markdown":"https://insights.sbomify.com/CVE-2022-49094/index.md","name":"CVE-2022-49094","record":{"aliases":["DEBIAN-CVE-2022-49094","GHSA-jf4f-5p54-w3hx","UBUNTU-CVE-2022-49094"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel TLS","requires_auth":"none","summary":"A slab-out-of-bounds read in the Linux kernel TLS module allows attackers to cause denial of service or potentially execute code via crafted network traffic.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/tls: fix slab-out-of-bounds bug in decrypt_internal\n\nThe memory size of tls_ctx-\u003erx.iv for AES128-CCM is 12 setting in\ntls_set_sw_offload().
