Bugzilla:
1590799: CVE-2018-5848 kernel: buffer overflow in drivers/net/wireless/ath/wil6210/wmi.c:wmi_set_ie() may lead to memory corruption
In the function wmi_set_ie() in the Linux kernel the length validation code does not handle unsigned integer overflow properly. As a result, a large value of the ‘ie_len’ argument can cause a buffer overflow and thus a memory corruption leading to a system crash or other or unspecified impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.
