When the tried_regions directory\nsetup is failed, the setup function ensures the reference for the tried\nregions directory is released.  Hence the error path should put references\non setup succeeded directory objects, starting from the stats directory. \nHowever, the error path is putting the tried_regions directory instead of\nthe stats directory.\n\nAs a direct result, the stats directory object is leaked.  Worse yet, if\nthe tried_regions directory setup failed from the initial allocation, the\nscheme->tried_regions field remains uninitialized.  The following\nkobject_put(&scheme->tried_regions->kobj) call in the error path will\ndereference the uninitialized memory.  The setup failures should not be\ncommon.  But once it happens, the consequence is quite bad.\n\nFix this issue by correctly putting the stats directory instead of the\ntried_regions directory.\n\nThe issue was discovered [1] by Sashiko.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/05ea83ee88ca70f8932906d9f2617ff996f45b50","https://git.kernel.org/stable/c/40a04601a3f66cabd6629c258a07af645a658865","https://git.kernel.org/stable/c/50a753171d255895e5dd41566986b48dcec06f31","https://git.kernel.org/stable/c/6b6b5d7c2c957136b92c00b77b7175259f13082b","https://git.kernel.org/stable/c/f63d6e5ba72aeacdee4fddc902bd7616cd62b919"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72176","score":0.00209,"percentile":0.11044,"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).
