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-2026-80748 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-2026-80748/ (Markdown: https://insights.sbomify.com/CVE-2026-80748/index.md)","id":"CVE-2026-80748","markdown":"https://insights.sbomify.com/CVE-2026-80748/index.md","name":"CVE-2026-80748","record":{"aliases":["BELL-CVE-2026-80748","DEBIAN-CVE-2026-80748","GHSA-rcvm-9rhr-j437","UBUNTU-CVE-2026-80748"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel MMC driver","requires_auth":"low_privilege","summary":"Incorrect scatterlist iteration in the Loongson2 MMC driver causes out-of-bounds memory access, potentially leading to system crashes or code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmmc: loongson2: Fix sg iteration in data reorder functions\n\nIn ls2k0500_mmc_reorder_cmd_data() and ls2k2000_mmc_reorder_cmd_data(),\nthe for_each_sg() macro already iterates over the scatterlist entries,\nwith 'sg' pointing to the current entry.
