In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7925: fix crash in reset link replay

During reset recovery, mt7925_vif_connect_iter() replays firmware state
for links tracked in mvif->valid_links. After MLO link changes or MCU
timeout recovery, the driver bitmap can temporarily contain a link whose
mac80211 bss_conf has already gone away.

This can pass a NULL bss_conf to mt76_connac_mcu_uni_add_dev(), matching
the crash where x1, the second argument, is NULL:

pc : mt76_connac_mcu_uni_add_dev+0x8c/0x1f8 [mt76_connac_lib]
lr : mt7925_vif_connect_iter+0x9c/0x168 [mt7925_common]
x2 : ffffff80a77f6018 x1 : 0000000000000000 x0 : ffffff8099402080
Call trace:
mt76_connac_mcu_uni_add_dev+0x8c/0x1f8 [mt76_connac_lib]
mt7925_vif_connect_iter+0x9c/0x168 [mt7925_common]
mt7925_mac_reset_work+0x264/0x2f8 [mt7925_common]

Skip missing bss_conf entries before replaying the link. Non-MLO AP/STA
reset replay is unchanged because the helper still returns &vif->bss_conf
for the legacy link.

Improper Control of Generation of Code ('Code Injection') 🎯 Medium

The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.

🛡️ Empfohlene Mitigation: Refactor your program so that you do not have to dynamically generate code.
