Published Nov 7, 2024 linux EPSS 0.21% (12th pctl) CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Overview

CVE-2024-50169 is a medium-severity vulnerability affecting linux linux_kernel. It was published on November 7, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

vsock: Update rx_bytes on read_skb()

Make sure virtio_transport_inc_rx_pkt() and virtio_transport_dec_rx_pkt()

calls are balanced (i.e. virtio_vsock_sock::rx_bytes doesn't lie) after

vsock_transport::read_skb().

While here, also inform the peer that we've freed up space and it has more

credit.

Failing to update rx_bytes after packet is dequeued leads to a warning on

SOCK_STREAM recv():

[ 233.396654] rx_queue is empty, but rx_bytes is non-zero

[ 233.396702] WARNING: CPU: 11 PID: 40601 at net/vmw_vsock/virtio_transport_common.c:589

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
