CVE-2019-19063

Priority
Description
Two memory leaks in the rtl_usb_probe() function in
drivers/net/wireless/realtek/rtlwifi/usb.c in the Linux kernel through
5.3.11 allow attackers to cause a denial of service (memory consumption),
aka CID-3f9361695113.
Ubuntu-Description
It was discovered that the Realtek rtlwifi USB device driver in the Linux
kernel did not properly deallocate memory in certain error conditions. A
local attacker could possibly use this to cause a denial of service (kernel
memory exhaustion).
