Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.2.1

Description A use-after-free issue was discovered in the Linux kernel, specifically in the drivers/net/wireless/intersil/p54/p54usb.c driver, caused by a malicious USB device. This issue can lead to a denial of service.

Recommendations For Linux kernel versions prior to 5.2.1, update to version 5.2.1 or later to resolve the issue. As a temporary workaround, consider disabling the use of USB devices from untrusted sources to minimize the risk of exploitation. Restrict access to the p54usb.c driver to minimize the risk of denial of service.
