CVE-2024-42114 — wifi: cfg80211: restrict NL80211_ATTR_TXQ_QUANTUM values

Affected: Linux, Siemens SIMATIC S7-1500 TM MFP - GNU/Linux subsystem

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")
