An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-10263 in the wild and no public exploit code.\n\nAffected product: Arm C1-Premium. 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-2025-10263/ (Markdown: https://insights.sbomify.com/CVE-2025-10263/index.md)","id":"CVE-2025-10263","markdown":"https://insights.sbomify.com/CVE-2025-10263/index.md","name":"CVE-2025-10263","record":{"aliases":["ALPINE-CVE-2025-10263","DEBIAN-CVE-2025-10263","GHSA-x9c8-763w-495x","ROOT-OS-DEBIAN-11-CVE-2025-10263","ROOT-OS-DEBIAN-12-CVE-2025-10263","UBUNTU-CVE-2025-10263"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Arm CPU cores","requires_auth":"none","summary":"Attackers can write to higher exception level resources on specific Arm CPU cores, enabling privilege escalation.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Arm","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-266","name":"Incorrect Privilege Assignment"},{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"Arm C1-Ultra, C1-Premium, Neoverse V3 \u0026 V3AE, Neoverse V2, Neoverse V1, Neoverse-N2, Neoverse-N1, Cortex-X925, Cortex-X4, Cortex-X3, Cortex-X2, Cortex-X1 \u0026 X1C, Cortex-A710, Cortex-A78, A78AE \u0026 A78C, Cortex-A77, Cortex-A76 \u0026 A76A may allow writes to resources owned by a higher exception level.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-10-23","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-10-23T04:42:54Z","kind":"github_poc","ref":"https://github.com/mikedejesushuembesrodriguez-max/erratumcheck","stars":0,"title":"NS2JB-CVE-2025-10263 erratum check "}],"tier":"poc_unverified"},"has_fix":true,"headline":"Privilege escalation in C1-Premium","id":"CVE-2025-10263","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Digiever｜NVR - Exposure of Sensitive Information","id":"CVE-2025-10264"},"packages":[],"prev":{"headline":"An unsanitized format validation vulnerability in Nokia SR Linux","id":"CVE-2025-10262"},"products":["C1-Premium","C1-Ultra","Cortex-A710","Cortex-A76","Cortex-A76AE","Cortex-A77","Cortex-A78","Cortex-A78AE","Cortex-A78C","Cortex-X1","Cortex-X1C","Cortex-X2","Cortex-X3","Cortex-X4","Cortex-X925","Neoverse N1","Neoverse N2","Neoverse V1","Neoverse V3","Neoverse V3AE"],"published":"2026-06-09","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-04","vendors":["Arm"]},"summary":"Attackers can write to higher exception level resources on specific Arm CPU cores, enabling privilege escalation.","url":"https://insights.sbomify.com/CVE-2025-10263/"}
