Details
An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This flaw allows a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that results in kmalloc data to be printed (and potentially leaked) to the kernel ring buffer (dmesg).
