It seems there was a simple way of\npassing it in binary all along, so use that and avoid the hexification.\n\nOpenBSD has been doing it like this from the beginning, so this should\nwork on all chips.\n\nAlso clear the structure before setting the PMK. This was leaking\nuninitialized stack contents to the device.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1687845eb8f37360a9ee849a3587ab659b090773","https://git.kernel.org/stable/c/2bc34facb90ceeff6f8c17d2006575a6d07c3825","https://git.kernel.org/stable/c/2fa3a5226b05e0a797c68b9609dcebe0cd236b27","https://git.kernel.org/stable/c/4e8dc0e5c7636efaadbd7e488acd34b4291c0431","https://git.kernel.org/stable/c/56c7e9c39bd54fd753c0c4b1ed10278cbd3a5f02"],"products":[],"source":"nvd","synced_at":"2026-10-28T19:37:43.506563291+00:00"},"epss":{"cve":"CVE-2023-53715","score":0.0021,"percentile":0.11145,"date":"2026-10-28"},"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).
