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

In this case, simply return an error instead, to indicate
that no data is available.
