"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath9k: hif_usb: fix memory leak of remain_skbs\n\nhif_dev->remain_skb is allocated and used exclusively in\nath9k_hif_usb_rx_stream(). It is implied that an allocated remain_skb is\nprocessed and subsequently freed (in error paths) only during the next\ncall of ath9k_hif_usb_rx_stream().\n\nSo, if the urbs are deallocated between those two calls due to the device\ndeinitialization or suspend, it is possible that ath9k_hif_usb_rx_stream()\nis not called next time and the allocated remain_skb is leaked. Our local\nSyzkaller instance was able to trigger that.\n\nremain_skb makes sense when receiving two consecutive urbs which are\nlogically linked together, i.e. a specific data field from the first skb\nindicates a cached skb to be allocated, memcpy'd with some data and\nsubsequently processed in the next call to ath9k_hif_usb_rx_stream(). Urbs\ndeallocation supposedly makes that link irrelevant so we need to free the\ncached skb in those cases.\n\nFix the leak by introducing a function to explicitly free remain_skb (if\nit is not NULL) when the rx urbs have been deallocated. remain_skb is NULL\nwhen it has not been allocated at all (hif_dev struct is kzalloced) or\nwhen it has been processed in next call to ath9k_hif_usb_rx_stream().\n\nFound by Linux Verification Center (linuxtesting.org) with Syzkaller."
