The buffer is not NUL-terminated, but recover_inode() and\nrecover_dentry() print it with %s.\n\nFor a 255-byte filename, recovery logging can read past i_name into the\nfollowing raw inode fields.\n\nPrint the name with a precision bounded by i_namelen and F2FS_NAME_LEN.","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/01027b2fcb74dade59fb833b51023f6593b6a9a2","https://git.kernel.org/stable/c/317d32e1a8deaf1c01c388badc667334c39e62ca","https://git.kernel.org/stable/c/35c5abccd0924b02ad34126f562d93c8d75b0831","https://git.kernel.org/stable/c/7ab1780074943508534343e1e5e5ab0c9ef9dd7b","https://git.kernel.org/stable/c/e754120f8ede55cc773ade108cf7e5b17c859c46"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-89838","score":0.00164,"percentile":0.05557,"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).
