{"cve":"CVE-2025-31936","nvd":{"published":"2026-08-11T17:17:43.500","modified":"2026-09-29T11:10:00.150","status":"Analyzed","description":"Improper handling of overlap between protected memory ranges for some Intel(R) Xeon(R) 6 processors when using Intel(R) TDX within SMM may allow an escalation of privilege. SMM adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present with special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:H/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":7.0},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:N","score":5.7},"cwes":["CWE-1260"],"references":["https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01379.html"],"products":["intel:xeon_6315p_firmware","intel:xeon_6325p_firmware","intel:xeon_6333p_firmware","intel:xeon_6337p_firmware","intel:xeon_6349p_firmware","intel:xeon_6353p_firmware","intel:xeon_6357p_firmware","intel:xeon_6369p_firmware","intel:xeon_6377p_firmware","intel:xeon_6503p-b_firmware","intel:xeon_6503p_firmware","intel:xeon_6505p_firmware","intel:xeon_6507p_firmware","intel:xeon_6511p_firmware","intel:xeon_6513p-b_firmware","intel:xeon_6515p_firmware","intel:xeon_6516p-b_firmware","intel:xeon_6517p_firmware","intel:xeon_6518p-b_firmware","intel:xeon_6520p_firmware","intel:xeon_6521p_firmware","intel:xeon_6523p-b_firmware","intel:xeon_6527p_firmware","intel:xeon_6530p_firmware","intel:xeon_6532p-b_firmware","intel:xeon_6533p-b_firmware","intel:xeon_6543p-b_firmware","intel:xeon_6544p-b_firmware","intel:xeon_6546p-b_firmware","intel:xeon_6548p-b_firmware","intel:xeon_6553p-b_firmware","intel:xeon_6556p-b_firmware","intel:xeon_6563p-b_firmware","intel:xeon_6706p-b_firmware","intel:xeon_6714p_firmware","intel:xeon_6716p-b_firmware","intel:xeon_6718p-b_firmware","intel:xeon_6724p_firmware","intel:xeon_6725p_firmware","intel:xeon_6726p-b_firmware","intel:xeon_6728p_firmware","intel:xeon_6730p_firmware","intel:xeon_6731p_firmware","intel:xeon_6732p_firmware","intel:xeon_6736p_firmware","intel:xeon_6737p_firmware","intel:xeon_6738p_firmware","intel:xeon_6740p_firmware","intel:xeon_6741p_firmware","intel:xeon_6745p_firmware"],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2025-31936","score":0.00098,"percentile":0.00736,"date":"2026-11-01"},"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).
