An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that results in kmalloc data being printed and potentially leaked to the kernel ring buffer (dmesg).
Se encontró una vulnerabilidad de lectura fuera de los límites en el subsistema NVMe-oF/TCP del kernel de Linux. Esta falla permite que un atacante remoto envíe un paquete TCP manipulado, lo que desencadena un desbordamiento del búfer que da como resultado que los datos kmalloc se impriman (y potencialmente se filtren) en el búfer de anillo del kernel (dmesg).
