      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7921/mt7925: fix NULL dereference in CSA beacon\n\nThis patch is based on a BUG as reported by Bongani Hlope at\nhttps://lore.kernel.org/all/20260502125824.425d7159@bongani-mini.home.org.za/\n\nWhen a channel-switch announcement (CSA) beacon is received,\ncfg80211 queues a wiphy work item that eventually calls\nmt7921_channel_switch_rx_beacon(). If the station disconnects\n(or the channel context is otherwise torn down) between the\ntime the work is queued and the time it runs, the driver's\ndev->new_ctx pointer can already have been cleared to NULL.\nmt7921_channel_switch_rx_beacon() then dereferences new_ctx\nunconditionally, triggering a NULL pointer dereference at\naddress 0x0:\n\n  BUG: kernel NULL pointer dereference, address: 0000000000000000\n  RIP: 0010:mt7921_channel_switch_rx_beacon+0x1f/0x100 [mt7921_common]\n\nThe same missing guard exists in mt7925_channel_switch_rx_beacon(),\nwhich shares the same code pattern introduced by the same commit.\n\nAdd an early-return NULL check for dev->new_ctx in both\nmt7921_channel_switch_rx_beacon() and\nmt7925_channel_switch_rx_beacon(). When new_ctx is NULL there is\nno pending channel switch to process, so returning immediately is\nthe correct and safe action.\n\nOops-Analysis: http://oops.fenrus.org/reports/lkml/20260502125824.425d7159@bongani-mini.home.org.za/report.html",
