4.4 · MEDIUM
Published Jul 30, 2024 linux CWE-667 EPSS 0.17% (7th pctl)

Overview

CVE-2024-42114 is a medium-severity vulnerability affecting linux linux_kernel. It was published on July 30, 2024 and has a CVSS 3.1 base score of 4.4 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.4, 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:

wifi: cfg80211: restrict NL80211_ATTR_TXQ_QUANTUM values

syzbot is able to trigger softlockups, setting NL80211_ATTR_TXQ_QUANTUM

to 2^31.

We had a similar issue in sch_fq, fixed with commit

d9e15a273306 ("pkt_sched: fq: do not accept silly TCA_FQ_QUANTUM")

watchdog: BUG: soft lockup - CPU#1 stuck for 26s! [kworker/1:0:24]
