Detail
| In the Linux kernel, the following vulnerability has been resolved: ath9k_htc: fix uninit value bugs Syzbot reported 2 KMSAN bugs in ath9k. All of them are caused by missing field initialization. In htc_connect_service() svc_meta_len and pad are not initialized. Based on code it looks like in current skb there is no service data, so simply initialize svc_meta_len to 0. htc_issue_send() does not initialize htc_frame_hdr::control array. Based on firmware code, it will initialize it by itself, so simply zero whole array to make KMSAN happy Fail logs: BUG: KMSAN: kernel-usb-infoleak in usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430 Uninit was created at: Bytes 4-7 of 18 are uninitialized Memory access of size 18 starts at ffff888027377e00 BUG: KMSAN: kernel-usb-infoleak in usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430 Uninit was created at: Bytes 16-17 of 18 are uninitialized Memory access of size 18 starts at ffff888027377e00 |
