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-2026-74651 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-2026-74651/ (Markdown: https://insights.sbomify.com/CVE-2026-74651/index.md)","id":"CVE-2026-74651","markdown":"https://insights.sbomify.com/CVE-2026-74651/index.md","name":"CVE-2026-74651","record":{"aliases":["BELL-CVE-2026-74651","DEBIAN-CVE-2026-74651","GHSA-849j-9cq7-9mpx","UBUNTU-CVE-2026-74651"],"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":"An out-of-bounds read in the rtl8723bs Wi-Fi driver allows attackers to read memory beyond the intended buffer via crafted management frames.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nstaging: rtl8723bs: fix OOB read in rtw_get_wpa_ie()\n\nrtw_get_wpa_ie() reads bytes at fixed offsets into a vendor-specific\ninformation element without checking that the element is long enough,\ncausing an out-of-bounds read for a short trailing IE.\n\nThe function locates a vendor-specific IE (EID 221) with rtw_get_ie()\nand then compares a 4-byte OUI+type at pbuf + 2 and reads a 2-byte\nversion word at pbuf + 6. Those accesses require the IE body to be at\nleast 6 bytes, but rtw_get_ie() only guarantees that the element fits\nwithin the buffer; it does not enforce a minimum body length. A\nvendor-specific IE whose length byte is 0 to 5, placed at the end of\nthe buffer, therefore makes these reads run past the end of the IE and\npast the end of the buffer itself.\n\nThe buffer holds information elements taken from received management\nframes and from the IE blob passed to rtw_cfg80211_set_wpa_ie(), which\nis kmemdup'd to its exact length, so the read can run off the end of\nthe allocation.\n\nThe sibling helpers rtw_get_sec_ie(), rtw_get_wapi_ie() and\nrtw_get_wps_ie() in this file already reject too-short vendor-specific\nIEs before their OUI memcmp(); rtw_get_wpa_ie() was never brought in\nline with them, and needs a minimum of 6 rather than 4 bytes because\nof the version word.
