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-2026-90017 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-2026-90017/ (Markdown: https://insights.sbomify.com/CVE-2026-90017/index.md)","id":"CVE-2026-90017","markdown":"https://insights.sbomify.com/CVE-2026-90017/index.md","name":"CVE-2026-90017","record":{"aliases":["AZL-101631","BELL-CVE-2026-90017","DEBIAN-CVE-2026-90017","GHSA-9fp4-x69f-gf9f","UBUNTU-CVE-2026-90017"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A missing length check in the rtl8723bs driver allows an attacker to trigger an out-of-bounds read, potentially disclosing kernel memory.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nstaging: rtl8723bs: fix OOB read in rtw_action_frame_parse()\n\nrtw_action_frame_parse() takes a frame_len parameter but never\nactually checks it before indexing into the frame body:\n\n\tconst u8 *frame_body = frame + sizeof(struct ieee80211_hdr_3addr);\n\t...\n\tc = frame_body[0];\n\t...\n\ta = frame_body[1];\n\nframe_body already points 24 bytes (sizeof(struct\nieee80211_hdr_3addr)) into frame, so reading frame_body[0] and\nframe_body[1] requires frame_len \u003e= 26.
