Vulnerability CVE-2024-41075
Published: 2024-07-29

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.
