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 cachefiles_open_file(), 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 cachefiles_create_tmpfile(), though
the "Inode already in use" warning won't be triggered, fix the leakage
anyway.

A flaw in the Linux kernel's cachefiles subsystem can lead to resource leakage due to improper handling of inodes during error conditions. Specifically, if an error occurs in functions like cachefiles_open_file() or cachefiles_create_tmpfile(), the associated ino
