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-2026-89977 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-2026-89977/ (Markdown: https://insights.sbomify.com/CVE-2026-89977/index.md)","id":"CVE-2026-89977","markdown":"https://insights.sbomify.com/CVE-2026-89977/index.md","name":"CVE-2026-89977","record":{"aliases":["DEBIAN-CVE-2026-89977","GHSA-c8v6-r4v4-jmq9","UBUNTU-CVE-2026-89977"],"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 error check in the Ethos-U accelerator driver probe function can lead to a null pointer dereference and kernel crash.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\naccel/ethosu: check MMIO mapping errors in probe\n\ndevm_platform_ioremap_resource() returns an error pointer when the register\nresource cannot be mapped. ethosu_probe() stores it and continues until\ninitialization dereferences it through MMIO accessors.\n\nReturn the mapping error before initializing the device.","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":"accel/ethosu: check MMIO mapping errors in probe","id":"CVE-2026-89977","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"accel/amdxdna: return early from a zero-length flush","id":"CVE-2026-89978"},"packages":[],"prev":{"headline":"accel/ethosu: fix job completion fence cleanup","id":"CVE-2026-89976"},"products":["Linux"],"published":"2026-09-16","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":"2026-10-19","vendors":["Linux"]},"summary":"A missing error check in the Ethos-U accelerator driver probe function can lead to a null pointer dereference and kernel crash.","url":"https://insights.sbomify.com/CVE-2026-89977/"}
