CVE-2022-49064 Details
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.
A vulnerability in the Linux kernel's cachefiles component has been addressed, concerning improper inode management during error handling. When an error occurs, the in-use flag for the inode is not correctly cleared, leading to issues when another cookie with the same index key is later processed. This can cause Cachefiles to erroneously report that the 'Inode is already in use'. Although this warning won't be triggered if the leakage happens during temporary file creation, the in-use flag should still be properly managed.
