Since we additionally aren't counting how\nmuch memory is used for stolen and we could in theory fill up the\nentire stolen area with DPT's, avoid using stolen and only use the\ndefault memory region.\n\nUsing stolen may also result in random system hangs under load.\n\n(cherry picked from commit a196406a3831291598fe8e73245914f7acffdfe0)","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/491c499295fb0b90308b230b0a1075dcdf7f4d12","https://git.kernel.org/stable/c/c457e2c845ccbf2224386029f3da4937ba424db0","https://git.kernel.org/stable/c/f03415030579163f791c978741af7f1f2f6510b7","https://git.kernel.org/stable/c/fc648757908304aedbad74f74bf58192aec383db"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:53.108888569+00:00"},"epss":{"cve":"CVE-2026-80915","score":0.00156,"percentile":0.04752,"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).
