This will cause a memory leak and denial of service.", "A flaw was found in the Linux kernel's mwifiex driver implementation when connecting to other WiFi devices in \"Test Mode.\" A kernel memory leak can occur if an error condition is met during the parameter negotiation. This issue can lead to a denial of service if multiple error conditions meeting the repeated connection attempts are attempted." ],
