| Subject: CVE-2023-53125: net: usb: smsc75xx: Limit packet length to skb->len |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: usb: smsc75xx: Limit packet length to skb->len |
| |
| Packet length retrieved from skb data may be larger than |
| the actual socket buffer length (up to 9026 bytes). In such |
| case the cloned skb passed up the network stack will leak |
| kernel memory contents. |
| |
| The Linux kernel CVE team has assigned CVE-2023-53125 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
