CVE-2022-48651

7.7 · HIGH
Published Apr 28, 2024 linux CWE-125 EPSS 0.25% (16th pctl)

Overview

CVE-2022-48651 is a high-severity vulnerability affecting linux linux_kernel. It was published on April 28, 2024 and has a CVSS 3.1 base score of 7.7 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.7, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical Description

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

ipvlan: Fix out-of-bound bugs caused by unset skb->mac_header

If an AF_PACKET socket is used to send packets through ipvlan and the

default xmit function of the AF_PACKET socket is changed from

dev_queue_xmit() to packet_direct_xmit() via setsockopt() with the option

name of PACKET_QDISC_BYPASS, the skb->mac_header may not be reset and

remains as the initial value of 65535, this may trigger slab-out-of-bounds

bugs as following:
