CVE-2019-10064
hostapd before 2.6, in EAP mode, makes calls to the rand() and random() standard library functions without any preceding srand() or srandom() call, which results in inappropriate use of deterministic values.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.84%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
