+Subject: [PATCH] P2P: Validate SSID element length before copying it
+ (CVE-2015-1863)
+
+This fixes a possible memcpy overflow for P2P dev->oper_ssid in
+p2p_add_device(). The length provided by the peer device (0..255 bytes)
+was used without proper bounds checking and that could have resulted in
+arbitrary data of up to 223 bytes being written beyond the end of the
+dev->oper_ssid[] array (of which about 150 bytes would be beyond the
+heap allocation) when processing a corrupted management frame for P2P
+peer discovery purposes.
+
+This could result in corrupted state in heap, unexpected program
+behavior due to corrupted P2P peer device information, denial of service
+due to process crash, exposure of memory contents during GO Negotiation,
+and potentially arbitrary code execution.
+
+Thanks to Google security team for reporting this issue and smart
+hardware research group of Alibaba security team for discovering it.
