A memory leak in the cx23888_ir_probe() function in drivers/media/pci/cx23885/cx23888-ir.c allows attackers to cause a denial of service (memory consumption) by triggering kfifo_alloc() failures
Created kernel tracking bugs for this issue:
Affects: fedora-all [bug 1775117]
This issue is rated as having Low impact because of the preconditions needed to trigger the resource cleanup code path (system-wide out-of-memory condition).
In order to mitigate this issue it is possible to prevent the affected code from being loaded by blacklisting the kernel module cx23885. For instructions relating to how to blacklist a kernel module refer to: https://access.redhat.com/solutions/41278 .
