Summary
fat: release buffer head after rebuilding parent
Details

In the Linux kernel, the following vulnerability has been resolved:

fat: release buffer head after rebuilding parent

fat_scan_logstart() leaves the matching directory entry's buffer head in sinfo.bh for the caller to release, just like fat_scan().

fat_rebuild_parent() uses the directory entry to rebuild the parent inode for the nostale_ro NFS export path, but does not release sinfo.bh after a successful scan. Release it once fat_build_inode() has consumed the directory entry data.
