And\nthe fix was similarly to temporarily set po->num to zero to keep\nthe socket unhooked until the lock is retaken.\n\nThe po->bind_lock in packet_set_ring and packet_notifier precede the\nintroduction of git history.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","score":4.7},"cwes":["CWE-362"],"references":["https://blog.calif.io/p/a-race-within-a-race-exploiting-cve","https://git.kernel.org/stable/c/01d3c8417b9c1b884a8a981a3b886da556512f36","https://git.kernel.org/stable/c/18f13f2a83eb81be349a9757ba2141ff1da9ad73","https://git.kernel.org/stable/c/7da733f117533e9b2ebbd530a22ae4028713955c","https://git.kernel.org/stable/c/7de07705007c7e34995a5599aaab1d23e762d7ca"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:07:46.309729541+00:00"},"epss":{"cve":"CVE-2025-38617","score":0.00398,"percentile":0.33717,"date":"2026-10-25"},"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).
