95164dc11b
A vulnerability was discovered in how wpa_supplicant processing P2P (Wi-Fi Direct) group information from active group owners. The actual parsing of that information validates field lengths appropriately, but processing of the parsed information misses a length check when storing a copy of the secondary device types. This can result in writing attacker controlled data into the peer entry after the area assigned for the secondary device type. The overflow can result in corrupting pointers for heap allocations. This can result in an attacker within radio range of the device running P2P discovery being able to cause unexpected behavior, including termination of the wpa_supplicant process and potentially arbitrary code execution. https://w1.fi/security/2020-2/wpa_supplicant-p2p-group-info-processing-vulnerability.txt Fixes: CVE-2021-0326 |
