CVE-2026-43156

The CVE-2026-43156 entry affects the Linux kernel USB Pegasus driver. The root cause is that pegasus_probe() built URBs using hardcoded endpoint pipes (RX bulk 1, TX bulk 2, status interrupt 3) without validating endpoint descriptors, allowing a malformed USB device to present endpoints with mism...
