CVE-2019-19068

Priority
Description
A memory leak in the rtl8xxxu_submit_int_urb() function in
drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.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-a2cdd07488e6.
Ubuntu-Description
It was discovered that the Realtek RTL8xxx USB Wi-Fi 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).
