However the inode\ncan aand does live beyond that point and it is possible that some of\nthe fs call back functions will be invoked after the reference has\nbeen put, which results in a race between freeing the data and\naccessing it through the fs.\n\nWhile the rawdata/loaddata is the most likely candidate to fail the\nrace, as it has the fewest references. If properly crafted it might be\npossible to trigger a race for the other types stored in i_private.\n\nFix this by moving the put of i_private referenced data to the correct\nplace which is during inode eviction.","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:H/A:H","score":7.8},"cwes":["CWE-362"],"references":["https://git.kernel.org/stable/c/13bc2772414d68e94e273dea013181a986948ddf","https://git.kernel.org/stable/c/2a732ed26fbd048e7925d227af8cf9ea43fb5cc9","https://git.kernel.org/stable/c/3ddb961d2929bbb3204a2bba21b5d8153cd3f7cc","https://git.kernel.org/stable/c/667df93769c02ff581c77d2d8f162147e719c557","https://git.kernel.org/stable/c/8e135b8aee5a06c52a4347a5a6d51223c6f36ba3"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-23411","score":0.00147,"percentile":0.03908,"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).
