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-2026-46155 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-2026-46155/ (Markdown: https://insights.sbomify.com/CVE-2026-46155/index.md)","id":"CVE-2026-46155","markdown":"https://insights.sbomify.com/CVE-2026-46155/index.md","name":"CVE-2026-46155","record":{"aliases":["AZL-88854","BELL-CVE-2026-46155","DEBIAN-CVE-2026-46155","GHSA-r5mc-mc43-5gch","UBUNTU-CVE-2026-46155"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel SMB client","requires_auth":"none","summary":"A malicious SMB server can trigger an out-of-bounds read in the Linux kernel SMB client, leaking adjacent kernel heap memory.","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":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/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\nsmb/client: fix out-of-bounds read in smb2_compound_op()\n\nIf a server sends a truncated response but a large OutputBufferLength, and\nterminates the EA list early, check_wsl_eas() returns success without\nvalidating that the entire OutputBufferLength fits within iov_len.\n\nThen smb2_compound_op() does:\n    memcpy(idata-\u003ewsl.eas, data[0], size[0]);\n\nWhere size[0] is OutputBufferLength.
