CVE-2024-58099

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved, specifically in the vmxnet3 module. The issue caused packet corruption when a BPF program for native XDP added an encapsulation header and transmitted the packet out the same interface. This resulted in corrupted packets being sent and subsequently dropped. The problem occurred because the vmxnet3 xdp xmit frame() function calculated an incorrect DMA address, assuming a fixed offset. The XDP BPF program could have moved xdp->data, requiring a dynamic offset calculation.

Recommendations To resolve the issue, update the Linux kernel to a version that includes the fix for the packet corruption in vmxnet3. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
