CVE-2024-42108

一、漏洞信息
漏洞编号：CVE-2024-42108
漏洞归属组件：kernel
漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.0,6.1.14,6.1.19,6.1.5,6.1.6,6.1.8,6.4.0,6.6.0
CVSS V2.0分值：
BaseScore：0.0 Low
Vector：CVSS：2.0/
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:net: rswitch: Avoid use-after-free in rswitch_poll()The use-after-free is actually in rswitch_tx_free(), which is inlined inrswitch_poll(). Since skb and gq->skbs[gq->dirty] are in fact thesame pointer, the skb is first freed using dev_kfree_skb_any(), then thevalue in skb->len is used to update the interface statistics.Let s move around the instructions to use skb->len before the skb isfreed.This bug is trivial to reproduce using KFENCE. It will trigger a splatevery few packets. A simple ARP request or ICMP echo request is enough.
