CVE-2015-0571 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. The WLAN (aka Wi-Fi) driver for the Linux kernel 3.x and 4.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, does not verify authorization for private SET IOCTL calls, which allows attackers to gain privileges via a crafted application, related to wlan_hdd_hostapd.c and wlan_hdd_wext.c.. EPSS estimates a 1.35% chance of exploitation in the next 30 days.
