Severity ?

5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k: hif_usb: clean up skbs if ath9k_hif_usb_rx_stream() fails Syzkaller detected a memory leak of skbs in ath9k_hif_usb_rx_stream(). While processing skbs in ath9k_hif_usb_rx_stream(), the already allocated skbs in skb_pool are not freed if ath9k_hif_usb_rx_stream() fails. If we have an incorrect pkt_len or pkt_tag, the input skb is considered invalid and dropped. All the associated packets already in skb_pool should be dropped and freed. Added a comment describing this issue. The patch also makes remain_skb NULL after being processed so that it cannot be referenced after potential free. The initialization of hif_dev fields which are associated with remain_skb (rx_remain_len, rx_transfer_len and rx_pad_len) is moved after a new remain_skb is allocated. Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

If we\nhave an incorrect pkt_len or pkt_tag, the input skb is considered invalid\nand dropped. All the associated packets already in skb_pool should be\ndropped and freed. Added a comment describing this issue.\n\nThe patch also makes remain_skb NULL after being processed so that it\ncannot be referenced after potential free. The initialization of hif_dev\nfields which are associated with remain_skb (rx_remain_len,\nrx_transfer_len and rx_pad_len) is moved after a new remain_skb is\nallocated.\n\nFound by Linux Verification Center (linuxtesting.org) with Syzkaller."
