CVE-2024-41075 Information

Description

In the Linux kernel the following vulnerability has been resolved:

cachefiles: add consistency check for copen/cread

This prevents malicious processes from completing random copen/cread requests and crashing the system. Added checks are listed below:

Generic copen can only complete open requests and cread can only complete read requests. For copen ondemand_id must not be 0 because this indicates that the request has not been read by the daemon. For cread the object corresponding to fd and req should be the same.
