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-2026-74693 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-2026-74693/ (Markdown: https://insights.sbomify.com/CVE-2026-74693/index.md)","id":"CVE-2026-74693","markdown":"https://insights.sbomify.com/CVE-2026-74693/index.md","name":"CVE-2026-74693","record":{"aliases":["BELL-CVE-2026-74693","DEBIAN-CVE-2026-74693","GHSA-2mgx-rhg3-xxxf","UBUNTU-CVE-2026-74693"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A missing length check in the Prestera network driver allows a local attacker to cause a denial of service by providing a malformed firmware image.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: prestera: validate firmware header length\n\nprestera_fw_hdr_parse() reads the firmware header before checking\nthat the firmware image contains that header.\n\nReject images shorter than struct prestera_fw_header before decoding the\nmagic and version fields.","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":"net: prestera: validate firmware header length","id":"CVE-2026-74693","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"net/ncsi: fix heap OOB read in NCSI_CMD_SEND_CMD payload length","id":"CVE-2026-74694"},"packages":[],"prev":{"headline":"net/smc: fix TOCTOU race between smc_listen_out() and listener close","id":"CVE-2026-74692"},"products":["Linux"],"published":"2026-08-22","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-22","vendors":["Linux"]},"summary":"A missing length check in the Prestera network driver allows a local attacker to cause a denial of service by providing a malformed firmware image.","url":"https://insights.sbomify.com/CVE-2026-74693/"}
