Last modified
CVE-2023-53068 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: net: usb: lan78xx: Limit packet length to skb->len Packet length retrieved from descriptor may be larger than the actual socket buffer length. In such case the cloned skb passed up the network stack will leak kernel memory contents. Additionally prevent integer underflow when size is less than ETH_FCS_LEN.. EPSS estimates a 0.16% chance of exploitation in the next 30 days.
