Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 6.6.58
Description:
A vulnerability has been resolved in the Linux kernel related to the
virtio net hdr to skb() function. The issue allowed a malicious packet to be injected through af packet, setting skb->csum start and thus the transport header to an incorrect value. This could potentially lead to security issues. The vulnerability was triggered by syzbot, which injected a malicious packet and set the transport header to an incorrect value.Recommendations:
To resolve the issue, update the Linux kernel to version 6.6.58 or later. As a temporary workaround, consider restricting access to the
af packet interface to minimize the risk of exploitation. Additionally, ensure that all network packets are properly validated and sanitized before processing to prevent potential security issues.Exploit
