In the Linux kernel, the following vulnerability has been resolved:
cachefiles: unmark inode in use in error path
Unmark inode in use if error encountered. If the in-use flag leakage occurs in cachefilesopenfile(), Cachefiles will complain "Inode already in use" when later another cookie with the same index key is looked up.
If the in-use flag leakage occurs in cachefilescreatetmpfile(), though the "Inode already in use" warning won't be triggered, fix the leakage anyway.
