kernel: wifi: mac80211_hwsim: drop short frames

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211hwsim: drop short frames While technically some control frames like ACK are shorter and end after Address 1, such frames shouldn't be forwarded through wmediumd or similar userspace, so require the full 3-address...

kernel: wifi: mac80211: don't return unset power in ieee80211_get_tx_power()

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: don't return unset power in ieee80211gettxpower We can get a UBSAN warning if ieee80211gettxpower returns the INTMIN value mac80211 internally uses for "unset power level". UBSAN: signed-integer-overflow in...

kernel: wifi: mac80211_hwsim: Fix possible NULL dereference

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211hwsim: Fix possible NULL dereference In a call to mac80211hwsimselecttxlink the sta pointer might be NULL, thus need to check that it is not NULL before accessing it...

CVE-2023-52644

In the Linux kernel, the following vulnerability has been resolved: wifi: b43: Stop/wake correct queue in DMA Tx path when QoS is disabled When QoS is disabled, the queue priority value will not map to the correct ieee80211 queue since there is only one queue. Stop/wake queue 0 when QoS is disabl...
