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-2026-31626 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-2026-31626/ (Markdown: https://insights.sbomify.com/CVE-2026-31626/index.md)","id":"CVE-2026-31626","markdown":"https://insights.sbomify.com/CVE-2026-31626/index.md","name":"CVE-2026-31626","record":{"aliases":["AZL-83717","BELL-CVE-2026-31626","DEBIAN-CVE-2026-31626","GHSA-cxgj-pqq4-q34h","ROOT-OS-DEBIAN-11-CVE-2026-31626","ROOT-OS-DEBIAN-12-CVE-2026-31626","ROOT-OS-UBUNTU-2204-CVE-2026-31626","ROOT-OS-UBUNTU-2404-CVE-2026-31626","UBUNTU-CVE-2026-31626"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"Uninitialized variable in rtl8723bs driver may cause unpredictable behavior; kernel maintainers should apply the patch.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-908","name":"Use of Uninitialized Resource"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nstaging: rtl8723bs: initialize le_tmp64 in rtw_BIP_verify()\n\nInitialize le_tmp64 to zero in rtw_BIP_verify() to prevent using\nuninitialized data.\n\nSmatch warns that only 6 bytes are copied to this 8-byte (u64)\nvariable, leaving the last two bytes uninitialized:\n\ndrivers/staging/rtl8723bs/core/rtw_security.c:1308 rtw_BIP_verify()\nwarn: not copying enough bytes for '\u0026le_tmp64' (8 vs 6 bytes)\n\nInitializing the variable at the start of the function fixes this\nwarning and ensures predictable behavior.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"staging: rtl8723bs: initialize le_tmp64 in rtw_BIP_verify()","id":"CVE-2026-31626","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"other","year":"2026"},"n_packages":0,"n_references":9,"next":{"headline":"i2c: s3c24xx: check the size of the SMBUS message before using it","id":"CVE-2026-31627"},"packages":[],"prev":{"headline":"HID: alps: fix NULL pointer dereference in alps_raw_event()","id":"CVE-2026-31625"},"products":["Linux"],"published":"2026-04-24","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"Uninitialized variable in rtl8723bs driver may cause unpredictable behavior; kernel maintainers should apply the patch.","url":"https://insights.sbomify.com/CVE-2026-31626/"}
