In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: don't return unset power in ieee80211_get_tx_power()
We can get a UBSAN warning if ieee80211_get_tx_power() returns the INT_MIN value mac80211 internally uses for "unset power level".
UBSAN: signed-integer-overflow in net/wireless/nl80211.c:3816:5 -2147483648 * 100 cannot be represented in type 'int' CPU: 0 PID: 20433 Comm: insmod Tainted: G WC OE Call Trace: dump_stack+0x74/0x92 ubsan_epilogue+0x9/0x50 handle_overflow+0x8d/0xd0 __ubsan_handle_mul_overflow+0xe/0x10 nl80211_send_iface+0x688/0x6b0 [cfg80211] [...] cfg80211_register_wdev+0x78/0xb0 [cfg80211] cfg80211_netdev_notifier_call+0x200/0x620 [cfg80211] [...] ieee80211_if_add+0x60e/0x8f0 [mac80211] ieee80211_register_hw+0xda5/0x1170 [mac80211]
In this case, simply return an error instead, to indicate that no data is available.
