This is a security hole. Fix it\nby clearing the s[12] array in thread_struct when fork.\n\nAs for kthread case, it's better to clear the s[12] array as well.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","score":7.1},"cwes":[],"references":["https://git.kernel.org/stable/c/358a68f98304b40b201ba5afe94c20355aa3dc68","https://git.kernel.org/stable/c/6510c78490c490a6636e48b61eeaa6fb65981f4b","https://git.kernel.org/stable/c/c4601d30f7d989b4f354df899ab85b5f7a750d30","https://git.kernel.org/stable/c/c5c0b3167537793a7cf936fb240366eefd2fc7fb","https://git.kernel.org/stable/c/cc36c7fa5d9384602529ba3eea8c5daee7be4dbc"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:22.920403922+00:00"},"epss":{"cve":"CVE-2022-49852","score":0.00208,"percentile":0.1089,"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).
