Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.2.10
Description The issue is related to a use-after-free bug in the Linux kernel, specifically in the drivers/hid/usbhid/hiddev.c driver. This bug can be triggered by a malicious USB device, potentially allowing an attacker to cause a denial of service.
