Loading vulnerability…
CVE-2023-53125 is an out-of-bounds read vulnerability in the Linux kernel's smsc75xx USB networking driver. A packet-length value retrieved from socket-buffer data can exceed the actual buffer length. The driver fails to constrain that value to skb->len, allowing a cloned socket buffer passed up the network stack to expose kernel memory beyond the valid packet data.
