"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nath9k_htc: fix uninit value bugs\n\nSyzbot reported 2 KMSAN bugs in ath9k. All of them are caused by missing\nfield initialization.\n\nIn htc_connect_service() svc_meta_len and pad are not initialized. Based\non code it looks like in current skb there is no service data, so simply\ninitialize svc_meta_len to 0.\n\nhtc_issue_send() does not initialize htc_frame_hdr::control array. Based\non firmware code, it will initialize it by itself, so simply zero whole\narray to make KMSAN happy\n\nFail logs:\n\nBUG: KMSAN: kernel-usb-infoleak in usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430\n usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430\n hif_usb_send_regout drivers/net/wireless/ath/ath9k/hif_usb.c:127 [inline]\n hif_usb_send+0x5f0/0x16f0 drivers/net/wireless/ath/ath9k/hif_usb.c:479\n htc_issue_send drivers/net/wireless/ath/ath9k/htc_hst.c:34 [inline]\n htc_connect_service+0x143e/0x1960 drivers/net/wireless/ath/ath9k/htc_hst.c:275\n...\n\nUninit was created at:\n slab_post_alloc_hook mm/slab.h:524 [inline]\n slab_alloc_node mm/slub.c:3251 [inline]\n __kmalloc_node_track_caller+0xe0c/0x1510 mm/slub.c:4974\n kmalloc_reserve net/core/skbuff.c:354 [inline]\n __alloc_skb+0x545/0xf90 net/core/skbuff.c:426\n alloc_skb include/linux/skbuff.h:1126 [inline]\n htc_connect_service+0x1029/0x1960 drivers/net/wireless/ath/ath9k/htc_hst.c:258\n...\n\nBytes 4-7 of 18 are uninitialized\nMemory access of size 18 starts at ffff888027377e00\n\nBUG: KMSAN: kernel-usb-infoleak in usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430\n usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430\n hif_usb_send_regout drivers/net/wireless/ath/ath9k/hif_usb.c:127 [inline]\n hif_usb_send+0x5f0/0x16f0 drivers/net/wireless/ath/ath9k/hif_usb.c:479\n htc_issue_send drivers/net/wireless/ath/ath9k/htc_hst.c:34 [inline]\n htc_connect_service+0x143e/0x1960 drivers/net/wireless/ath/ath9k/htc_hst.c:275\n...\n\nUninit was created at:\n slab_post_alloc_hook mm/slab.h:524 [inline]\n slab_alloc_node mm/slub.c:3251 [inline]\n __kmalloc_node_track_caller+0xe0c/0x1510 mm/slub.c:4974\n kmalloc_reserve net/core/skbuff.c:354 [inline]\n __alloc_skb+0x545/0xf90 net/core/skbuff.c:426\n alloc_skb include/linux/skbuff.h:1126 [inline]\n htc_connect_service+0x1029/0x1960 drivers/net/wireless/ath/ath9k/htc_hst.c:258\n...\n\nBytes 16-17 of 18 are uninitialized\nMemory access of size 18 starts at ffff888027377e00"
