Description Guilherme de Almeida Suckevicz 2019-11-25 14:22:28 UTC
A memory leak in the ath10k_usb_hif_tx_sg() function in drivers/net/wireless/ath/ath10k/usb.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures, aka CID-b8d17e7d93d2.
