  "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.",
