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-2026-72238 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-2026-72238/ (Markdown: https://insights.sbomify.com/CVE-2026-72238/index.md)","id":"CVE-2026-72238","markdown":"https://insights.sbomify.com/CVE-2026-72238/index.md","name":"CVE-2026-72238","record":{"aliases":["BELL-CVE-2026-72238","DEBIAN-CVE-2026-72238","GHSA-phw4-wh3r-2wj6","UBUNTU-CVE-2026-72238"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"none","summary":"An attacker with local access or control over boot parameters can cause a system hang during early boot by specifying an invalid UART baud rate.","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\nx86/boot: Validate console=uart8250 baud rate to fix early boot hang\n\nWhen the baud rate is empty, 0, invalid, or overflows to 0 when stored\nas an int, the system will hang during early boot because of a division\nby zero in early_serial_init().\n\nFall back to DEFAULT_BAUD when the resulting baud rate is 0 to prevent\nan early system hang.","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":"x86/boot: Validate console=uart8250 baud rate to fix early boot hang","id":"CVE-2026-72238","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":"x86/virt/sev: Revert \"Drop WBINVD before setting MSR_AMD64_SYSCFG_SNP_EN\"","id":"CVE-2026-72239"},"packages":[],"prev":{"headline":"perf/x86/amd/brs: Fix kernel address leakage","id":"CVE-2026-72237"},"products":["Linux"],"published":"2026-08-15","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":"2026-08-17","vendors":["Linux"]},"summary":"An attacker with local access or control over boot parameters can cause a system hang during early boot by specifying an invalid UART baud rate.","url":"https://insights.sbomify.com/CVE-2026-72238/"}
