It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-90803 exists.\n\nAffected product: Gnu Binutils. 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-2026-90803/ (Markdown: https://insights.sbomify.com/CVE-2026-90803/index.md)","id":"CVE-2026-90803","markdown":"https://insights.sbomify.com/CVE-2026-90803/index.md","name":"CVE-2026-90803","record":{"aliases":["DEBIAN-CVE-2026-90803","ECHO-392a-f089-3bab","GHSA-fw55-q7rw-84f9","UBUNTU-CVE-2026-90803"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GNU Binutils linker","requires_auth":"low_privilege","summary":"A buffer overflow in the GNU Binutils linker allows local attackers to execute arbitrary code or cause a denial of service via crafted ELF files.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[{"product":"binutils","vendor":"gnu"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A security vulnerability has been detected in GNU Binutils 2.47. Affected by this vulnerability is the function elf_x86_64_relocate_section of the file bfd/elf64-x86-64.c of the component ld. Such manipulation of the argument roff leads to buffer overflow. An attack has to be approached locally. The exploit has been disclosed publicly and may be used. Upgrading to version 2.48 addresses this issue. The name of the patch is 471130b39c03623ec6d78ece377ff4da3f6bfe7b.
