Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-90154 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-90154/ (Markdown: https://insights.sbomify.com/CVE-2026-90154/index.md)","id":"CVE-2026-90154","markdown":"https://insights.sbomify.com/CVE-2026-90154/index.md","name":"CVE-2026-90154","record":{"aliases":["AZL-102420","BELL-CVE-2026-90154","DEBIAN-CVE-2026-90154","GHSA-c8qh-mfc7-v6c7","UBUNTU-CVE-2026-90154"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel SMB","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel ksmbd module allows attackers to disrupt SMB sessions, causing denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: scope session state changes to bound connections\n\nksmbd_all_conn_set_status() treats every connection whose transient\nbinding flag is set as belonging to the target SessionId.
