CVE-2026-68196

CVE-2026-68196 affects the Linux kernel wilc1000 Wi-Fi driver. A malformed association response can lead to an out-of-bounds read due to improper validation when computing trailing IE length (ies_len = buffer_len - sizeof(*res)) without verifying buffer_len against the fixed header. Short frames ...
