CVE-2024-53147: exfat: fix out-of-bounds access of directory entries
In the Linux kernel, the following vulnerability has been resolved:
exfat: fix out-of-bounds access of directory entries
In the case of the directory size is greater than or equal to the cluster size, if startclu becomes an EOF cluster(an invalid cluster) due to file system corruption, then the directory entry where ei->hintfemp.eidx hint is outside the directory, resulting in an out-of-bounds access, which may cause further file system corruption.
This commit adds a check for startclu, if it is an invalid cluster, the file or directory will be treated as empty.
