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.","cvssScore":7.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/01027b2fcb74dade59fb833b51023f6593b6a9a2","tags":[]},{"url":"https://git.kernel.org/stable/c/317d32e1a8deaf1c01c388badc667334c39e62ca","tags":[]},{"url":"https://git.kernel.org/stable/c/35c5abccd0924b02ad34126f562d93c8d75b0831","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
