CVE-2022-49064 Information

Description

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.
