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-2026-74380 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-2026-74380/ (Markdown: https://insights.sbomify.com/CVE-2026-74380/index.md)","id":"CVE-2026-74380","markdown":"https://insights.sbomify.com/CVE-2026-74380/index.md","name":"CVE-2026-74380","record":{"aliases":["BELL-CVE-2026-74380","DEBIAN-CVE-2026-74380","GHSA-jqc5-8mvc-pp3w","UBUNTU-CVE-2026-74380"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"An integer overflow in the Linux kernel host1x driver can cause incorrect error handling, potentially leading to a denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ngpu: host1x: Fix iommu_map_sgtable() return value check\n\nCommit \"iommu: return full error code from iommu_map_sg[_atomic]()\"\nchanged iommu_map_sgtable() to return an ssize_t and negative values\nin error cases, rather than a size_t and a zero.\n\npin_job() also was incorrectly assigning to 'int', which could cause\noverflows into negative values.\n\nUpdate pin_job() to correctly check for errors from iommu_map_sgtable.","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":"gpu: host1x: Fix iommu_map_sgtable() return value check","id":"CVE-2026-74380","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"gpu: host1x: Allow entries in BO caches to be freed","id":"CVE-2026-74381"},"packages":[],"prev":{"headline":"dax/kmem: account for partial discontiguous resource upon removal","id":"CVE-2026-74379"},"products":["Linux"],"published":"2026-08-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-16","vendors":["Linux"]},"summary":"An integer overflow in the Linux kernel host1x driver can cause incorrect error handling, potentially leading to a denial of service.","url":"https://insights.sbomify.com/CVE-2026-74380/"}
