It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-53082 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-2026-53082/ (Markdown: https://insights.sbomify.com/CVE-2026-53082/index.md)","id":"CVE-2026-53082","markdown":"https://insights.sbomify.com/CVE-2026-53082/index.md","name":"CVE-2026-53082","record":{"aliases":["BELL-CVE-2026-53082","DEBIAN-CVE-2026-53082","GHSA-33fq-h3x2-m8v9","ROOT-OS-DEBIAN-11-CVE-2026-53082","ROOT-OS-DEBIAN-12-CVE-2026-53082","ROOT-OS-UBUNTU-2204-CVE-2026-53082","ROOT-OS-UBUNTU-2404-CVE-2026-53082","UBUNTU-CVE-2026-53082"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"An attacker can read uninitialized kernel memory via the hamradio 6pack driver due to improper handling of TTY error flags.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-908","name":"Use of Uninitialized Resource"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: hamradio: 6pack: fix uninit-value in sixpack_receive_buf\n\nsixpack_receive_buf() does not properly skip bytes with TTY error flags.\nThe while loop iterates through the flags buffer but never advances the\ndata pointer (cp), and passes the original count (including error bytes)\nto sixpack_decode().
