CVE-2024-41075

Summary

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.
