Linux Distros Unpatched Vulnerability : CVE-2026-23082

medium Nessus Plugin ID 298328

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - In the Linux kernel, the following vulnerability has been resolved: can: gs_usb:
 gs_usb_receive_bulk_callback(): unanchor URL on usb_submit_urb() error In commit 7352e1d5932a (can:
 gs_usb: gs_usb_receive_bulk_callback(): fix URB memory leak), the URB was re-anchored before usb_submit_urb() in gs_usb_receive_bulk_callback() to prevent a leak of this URB during cleanup. However, this patch did not take into account that usb_submit_urb() could fail. The URB remains anchored and usb_kill_anchored_urbs(&parent->rx_submitted) in gs_can_close() loops infinitely since the anchor list never becomes empty. To fix the bug, unanchor the URB when an usb_submit_urb() error occurs, also print an info message. (CVE-2026-23082)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
