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", "affected": [ { "vendor": "Linux", "product": "Linux", "defaultStatus": "unaffected", "versions": [ { "version": "fb9987d0f748c983bb795a86f47522313f701a08", "status": "affected", "versionType": "git", "lessThan": "5c2a6a8daa17a3f65b38b9a5574bb362c13fa1d9" }, { "version": "fb9987d0f748c983bb795a86f47522313f701a08", "status": "affected", "versionType": "git", "lessThan": "e352acdd378e9263cc4c6018e588f2dac7161d07" }, { "version": "fb9987d0f748c983bb795a86f47522313f701a08", "status": "affected", "versionType": "git", "lessThan": "ee4222052a76559c20e821bc3519cefb58b6d3e9" }, { "version": "fb9987d0f748c983bb795a86f47522313f701a08", "status": "affected", "versionType": "git", "lessThan": "4d244b731188e0b63fc40a9d2dec72e9181fb37c" }, { "version": "fb9987d0f748c983bb795a86f47522313f701a08", "status": "affected", "versionType": "git", "lessThan": "11f11ac281f0c0b363d2940204f28bae0422ed71" }, { "version": "fb9987d0f748c983bb795a86f47522313f701a08", "status": "affected", "versionType": "git", "lessThan": "0b700f7d06492de34964b6f414120043364f8191" }, { "version": "fb9987d0f748c983bb795a86f47522313f701a08", "status": "affected", "versionType": "git", "lessThan": "7da6169b6ebb75816b57be3beb829afa74f3b4b6" }, { "version": "fb9987d0f748c983bb795a86f47522313f701a08", "status": "affected", "versionType": "git", "lessThan": "5abf2b761b998063f5e2bae93fd4ab10e2a80f10" }, { "version": "fb9987d0f748c983bb795a86f47522313f701a08", "status": "affected", "versionType": "git", "lessThan": "d1e0df1c57bd30871dd1c855742a7c346dbca853" } ] }, { "vendor": "Linux", "product": "Linux", "defaultStatus": "affected", "versions": [ { "version": "2.6.35", "status": "affected" }, { "version": "0", "status": "unaffected", "versionType": "semver", "lessThan": "2.6.35" }, { "version": "4.9.311", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "4.9.*" }, { "version": "4.14.276", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "4.14.*" }, { "version": "4.19.238", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "4.19.*" }, { "version": "5.4.189", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.4.*" }, { "version": "5.10.110", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.10.*" }, { "version": "5.15.33", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.15.*" }, { "version": "5.16.19", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.16.*" }, { "version": "5.17.2", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.17.*" }, { "version": "5.18", "status": "unaffected", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*" } ] } ] } } }
