This allows an attacker to read a limited \nquantity of Secure stack contents with an impact on confidentiality. \nThis issue is specific to code generated using LLVM-based compilers.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","score":3.7},"cwes":["CWE-226"],"references":["https://developer.arm.com/Arm%20Security%20Center/Cortex-M%20Security%20Extensions%20Vulnerability"],"products":["arm:arm_compiler_for_embedded","arm:arm_compiler_for_embedded_fusa","arm:arm_compiler_for_functional_safety","arm:clang"],"source":"nvd","synced_at":"2026-10-19T21:56:33.105311382+00:00"},"epss":{"cve":"CVE-2024-7883","score":0.00468,"percentile":0.40525,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
