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-2024-53185 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-2024-53185/ (Markdown: https://insights.sbomify.com/CVE-2024-53185/index.md)","id":"CVE-2024-53185","markdown":"https://insights.sbomify.com/CVE-2024-53185/index.md","name":"CVE-2024-53185","record":{"aliases":["AZL-54824","BELL-CVE-2024-53185","DEBIAN-CVE-2024-53185","GHSA-qj49-7rgr-pfmq","UBUNTU-CVE-2024-53185"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Linux kernel SMB client","requires_auth":"none","summary":"A null pointer dereference in the Linux kernel SMB client causes a crash when mounting shares with specific encryption settings.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"},{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: fix NULL ptr deref in crypto_aead_setkey()\n\nNeither SMB3.0 or SMB3.02 supports encryption negotiate context, so\nwhen SMB2_GLOBAL_CAP_ENCRYPTION flag is set in the negotiate response,\nthe client uses AES-128-CCM as the default cipher.
