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-2026-80874 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-2026-80874/ (Markdown: https://insights.sbomify.com/CVE-2026-80874/index.md)","id":"CVE-2026-80874","markdown":"https://insights.sbomify.com/CVE-2026-80874/index.md","name":"CVE-2026-80874","record":{"aliases":["DEBIAN-CVE-2026-80874","GHSA-c596-8cgj-hv56","UBUNTU-CVE-2026-80874"],"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":"none","summary":"Improper memory reservation for inline ECC carveouts in the Linux kernel can lead to system instability and denial of service under high DRAM utilization.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\narm64: dts: renesas: ironhide: Describe inline ECC carveouts\n\nThe DBSC5 DRAM controller protects DRAM content using inline ECC.\nThe inline ECC utilizes areas of DRAM for its operation, which are\nin the DRAM address range, but must not be accessed or modified.\nDescribe the inline ECC carveout areas used by the DBSC5 controller\non this hardware as reserved-memory, which must not be accessed.\nInclude DRAM areas which are unprotected by ECC as well, those are\nparts of the DRAM which directly precede the ECC carveout.\n\nIn case of high DRAM utilization, unless the inline ECC carveouts\nare properly reserved, Linux may use and corrupt the memory used\nby the DBSC5 DRAM controller for inline ECC, which would lead to\nthe system becoming unstable.","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":"arm64: dts: renesas: ironhide: Describe inline ECC carveouts","id":"CVE-2026-80874","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"ipvs: use parsed transport offset in TCP state lookup","id":"CVE-2026-80875"},"packages":[],"prev":{"headline":"KVM: arm64: nv: Write ESR_EL2 for injected nested SError exceptions","id":"CVE-2026-80873"},"products":["Linux"],"published":"2026-09-04","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":"2026-09-04","vendors":["Linux"]},"summary":"Improper memory reservation for inline ECC carveouts in the Linux kernel can lead to system instability and denial of service under high DRAM utilization.","url":"https://insights.sbomify.com/CVE-2026-80874/"}
