wifi: cfg80211: restrict NL80211_ATTR_TXQ_QUANTUM values
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!
