kernel: wifi: mac80211: Fix deadlock in ieee80211_sta_ps_deliver_wakeup()

A vulnerability was found in the Linux kernel's mac80211 component within the ieee80211stapsdeliverwakeup function, where improper locking of the sta-pslock can lead to a deadlock condition, which occurs because the function uses a spin lock without preventing softirq execution on the same CPU,...

CVE-2024-43911 wifi: mac80211: fix NULL dereference at band check in starting tx ba session

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fix NULL dereference at band check in starting tx ba session In MLD connection, linkdata/linkconf are dynamically allocated. They don't point to vif-bssconf. So, there will be no chanreq assigned to vif-bssconf an...

CVE-2024-36921 wifi: iwlwifi: mvm: guard against invalid STA ID on removal

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: guard against invalid STA ID on removal Guard against invalid station IDs in iwlmvmmldrmstaid as that would result in out-of-bounds array accesses. This prevents issues should the driver get into a bad state...

The vulnerability of the sta_info_alloc() function in the Linux kernel’s mac80211 stack allows a hacker to cause a service failure.

The vulnerability of the stainfoalloc function in the net/mac80211/stainfo.c module, which is part of the mac80211 stack implemented in Linux kernel, can lead to a potential memory leak. Exploiting this vulnerability could allow an attacker to cause a service failure remotely...
