Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.3.11

Description The issue is related to a lack of protection for service data in the Linux kernel's drivers/net/can/usb/peak usb/pcan usb core.c driver. It can be exploited by a malicious USB device, potentially allowing an attacker to disclose protected information.

Recommendations For Linux kernel versions prior to 5.3.11, update to version 5.3.11 or later to resolve the issue. As a temporary workaround, consider restricting the use of USB devices from untrusted sources to minimize the risk of exploitation.
