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-2026-64536 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-2026-64536/ (Markdown: https://insights.sbomify.com/CVE-2026-64536/index.md)","id":"CVE-2026-64536","markdown":"https://insights.sbomify.com/CVE-2026-64536/index.md","name":"CVE-2026-64536","record":{"aliases":["AZL-93959","BELL-CVE-2026-64536","DEBIAN-CVE-2026-64536","GHSA-rwmp-xmg8-8r93","ROOT-OS-DEBIAN-12-CVE-2026-64536","UBUNTU-CVE-2026-64536"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"Out-of-bounds reads in the rtl8723bs Wi-Fi driver allow attackers to cause denial of service or leak kernel memory via crafted Information Elements.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/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\nstaging: rtl8723bs: fix OOB reads in is_ap_in_tkip() IE loop\n\nThe loop in is_ap_in_tkip() iterates over IEs without verifying that\nenough bytes remain before dereferencing the IE header or its payload:\n\n- pIE-\u003eelement_id and pIE-\u003elength are read without checking that\n  i + sizeof(*pIE) \u003c= ie_length, so a truncated IE at the end of the\n  buffer causes an OOB read.\n\n- For WLAN_EID_VENDOR_SPECIFIC the code compares pIE-\u003edata + 12,\n  which requires pIE-\u003elength \u003e= 16.
