When a context has performed a\nhandover, the console SRCU read lock is released and the pointer to the\nconsole struct might now be invalid. Therefore, after calling\nnbcon_legacy_emit_next_record() or console_emit_next_record(), it is\nnecessary to check if a handover occurred _before_ further @con usage.\n\nSashiko pointed out that console_flush_one_record() was not doing this.\n\nIn console_flush_one_record(), after emitting a record, move the further\nusage of @con after the handover check.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/36630cafbeede0b64c370edb2f7b4094327ee1e0","https://git.kernel.org/stable/c/8f194dee0c0d1223255bae1429e1939882f540fc","https://git.kernel.org/stable/c/f0104a7b730de32eefb3d4a27279592b5504ad59","https://git.kernel.org/stable/c/fbf9bb81b21537ede387a31cc586f1d2ce66a74e"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-93134","score":0.00209,"percentile":0.10937,"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).
