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-2026-41514 in the wild and no public exploit code.\n\nAffected product: OP-TEE optee_os. 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-2026-41514/ (Markdown: https://insights.sbomify.com/CVE-2026-41514/index.md)","id":"CVE-2026-41514","markdown":"https://insights.sbomify.com/CVE-2026-41514/index.md","name":"CVE-2026-41514","record":{"aliases":["DEBIAN-CVE-2026-41514","GHSA-qw4r-9wj9-q23r","UBUNTU-CVE-2026-41514"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"OP-TEE Trusted Execution Environment","requires_auth":"low_privilege","summary":"An attacker can recover RSA-OAEP plaintext via a padding oracle in the Hisilicon HPRE driver, affecting OP-TEE on specific hardware.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"op-tee","vendor":"trustedfirmware"}],"cvss":{"score":2.5,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-208","name":"Observable Timing Discrepancy"}],"description":"OP-TEE is a Trusted Execution Environment (TEE) designed as companion to a non-secure Linux kernel running on Arm; Cortex-A cores using the TrustZone technology. Starting in version 4.5.0 and prior to version 4.11.0, the RSA-OAEP decryption implementation in the Hisilicon HPRE crypto driver uses non-constant-time `memcmp()` for label hash verification and has multiple distinguishable error paths. This creates a Manger-style padding oracle that allows an attacker to recover RSA-OAEP plaintext with approximately 1000-2000 adaptive chosen ciphertext queries. Only affects plat-d06 with `CFG_HISILICON_ACC_V3=y`, which seems to be disabled by default. Version 4.11.0 contains a patch. As a workaround, disable Hisilicon HPRE RSA driver with `CFG_HISILICON_ACC_V3=n`.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"OP-TEE: RSA-OAEP padding oracle in Hisilicon HPRE driver enables plaintext recovery","id":"CVE-2026-41514","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"OP-TEE: RSA-OAEP padding oracle in NXP CAAM driver enables plaintext recovery","id":"CVE-2026-41515"},"packages":[],"prev":{"headline":"Horilla: Open Redirect via Unvalidated `next` Parameter in Notification Endpoints","id":"CVE-2026-41513"},"products":["optee_os"],"published":"2026-07-06","related":[{"cvss_score":9.8,"headline":"Memory corruption in OP-TEE","id":"CVE-2019-1010292","kev_date_added":null,"published":"2019-07-16"},{"cvss_score":9.8,"headline":"Memory corruption in OP-TEE","id":"CVE-2019-1010293","kev_date_added":null,"published":"2019-07-15"},{"cvss_score":9.8,"headline":"Linaro/OP-TEE OP-TEE 3.3.0 and earlier is affected by: Buffer Overflow.","id":"CVE-2019-1010295","kev_date_added":null,"published":"2019-07-15"},{"cvss_score":9.8,"headline":"Memory corruption in OP-TEE","id":"CVE-2019-1010296","kev_date_added":null,"published":"2019-07-15"},{"cvss_score":9.8,"headline":"Memory corruption in OP-TEE","id":"CVE-2019-1010297","kev_date_added":null,"published":"2019-07-15"},{"cvss_score":9.8,"headline":"Memory corruption in OP-TEE","id":"CVE-2019-1010298","kev_date_added":null,"published":"2019-07-15"},{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2019-25052","kev_date_added":null,"published":"2021-08-11"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-07","vendors":["OP-TEE"]},"summary":"An attacker can recover RSA-OAEP plaintext via a padding oracle in the Hisilicon HPRE driver, affecting OP-TEE on specific hardware.","url":"https://insights.sbomify.com/CVE-2026-41514/"}
