In __wlan_hdd_cfg80211_vendor_scan() in all Android releases from CAF using the Linux kernel (Android for MSM, Firefox OS for MSM, QRD Android) before security patch level 2018-07-05, when SCAN_SSIDS and QCA_WLAN_VENDOR_ATTR_SCAN_FREQUENCIES are parsed, a buffer overwrite can potentially occur.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
