| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A memory leak exists in the Linux kernel’s USB network driver for the rtl8150 chip. Specifically, within the
async set registers() function, a memory leak occurs when usb submit urb() fails. The async req structure and the URB are not freed in the error path, leading to a memory leak. The async set reg cb() completion callback, responsible for freeing these allocations, is only invoked upon successful URB submission and completion. If submission fails, the callback is bypassed, and the memory remains allocated. The issue is resolved by freeing the URB and request structure in the error path when usb submit urb() fails.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
