The EAP-pwd server and peer implementation in hostapd and wpa_supplicant 1.0 through 2.4 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted (1) Commit or (2) Confirm message payload.
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.
