CVE-2026-53105 Details
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7925: prevent NULL vif dereference in mt7925_mac_write_txwi Check for a NULL `vif` before accessing `ieee80211_vif_is_mld(vif)` to avoid a potential kernel panic in scenarios where `vif` might not be initialized.
A vulnerability in the Linux kernel's Wi-Fi MT76 MT7925 driver can lead to a NULL pointer dereference, causing a potential kernel panic. This issue arises in the 'mt7925_mac_write_txwi' function, where the code fails to check if the 'vif' (virtual interface) pointer is NULL before accessing it. In scenarios where 'vif' is not properly initialized, this oversight can lead to a crash.
