CVE-2025-68307

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The CAN driver within the Linux kernel contains an issue in the gs usb xmit callback() function related to the handling of failed transmitted URBs. The driver does not properly clean up after failed URB transfers, leading to a reduction in available URBs with each error. This can result in decreased performance and eventually a complete halt in transmission. Proper cleanup involves increasing network device statistics, marking the echo sbk as free, freeing the driver's context, performing accounting, and waking the send queue.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
