An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-7762 in the wild and no public exploit code.\n\nAffected product: Morse Micro HaLowLink 2. 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-2026-7762/ (Markdown: https://insights.sbomify.com/CVE-2026-7762/index.md)","id":"CVE-2026-7762","markdown":"https://insights.sbomify.com/CVE-2026-7762/index.md","name":"CVE-2026-7762","record":{"aliases":["GHSA-qm6x-8r68-vvv2"],"analysis":{"component_type":"kernel","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"HaLow Wi-Fi driver","requires_auth":"none","summary":"Unauthenticated attackers can cause kernel panic or execute code via crafted Wi-Fi frames due to a heap buffer overflow in the HaLow driver.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Bugcrowd","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"A heap-based buffer overflow vulnerability in the dot11ah.ko HaLow Wi-Fi kernel driver in Morse Micro HaLowLink 2 software versions prior to 2.11.13 allows an unauthenticated attacker within radio range to cause a Denial of Service (kernel panic) or potentially achieve Remote Code Execution via a crafted 802.11ah beacon or probe response frame containing a malformed S1G Capabilities Information Element (IE element ID 0xD9).
