CVE-2020-15393

Priority

Description

In the Linux kernel 4.4 through 5.7.6, usbtest_disconnect in
drivers/usb/misc/usbtest.c has a memory leak, aka CID-28ebeb8db770.

Ubuntu-Description

Kyungtae Kim discovered that the USB testing driver in the Linux kernel did
not properly deallocate memory on disconnect events. A physically proximate
attacker could use this to cause a denial of service (memory exhaustion).
