CVE-2023-53226
In the Linux kernel, the following vulnerability has been resolved: wifi: mwifiex: Fix OOB and integer underflow when rx packets Make sure mwifiex_process_mgmt_packet, mwifiex_process_sta_rx_packet and mwifiex_process_uap_rx_packet, mwifiex_uap_queue_bridged_pkt and mwifiex_process_rx_packet not out-of-bounds access the skb->data buffer.
CVE-2023-53257
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: check S1G action frame size Before checking the action code, check that it even exists in the frame.
CVE-2025-39864
In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: fix use-after-free in cmp_bss() Following bss_free() quirk introduced in commit 776b3580178f ("cfg80211: track hidden SSID networks properly"), adjust cfg80211_update_known_bss() to free the last beacon frame elements only if they're not shared via the corresponding 'hidden_beacon_bss' pointer.
