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.","published":"2026-09-16T10:31:12.746Z","modified":"2026-09-18T03:48:33.127522743Z","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"7.2.5"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/01027b2fcb74dade59fb833b51023f6593b6a9a2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/317d32e1a8deaf1c01c388badc667334c39e62ca"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89838.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89838"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-18T03:48:33.127522743Z"}}
