Echo: linux: security update to 6.1.162-1

medium Tenable Self-Hosted Container Security Plugin ID 457083

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: can: mcba_usb:
 mcba_usb_read_bulk_callback(): fix URB memory leak Fix similar memory leak as in commit 7352e1d5932a
 ("can: gs_usb: gs_usb_receive_bulk_callback(): fix URB memory leak"). In mcba_usb_probe() ->
 mcba_usb_start(), the URBs for USB-in transfers are allocated, added to the priv->rx_submitted anchor and
 submitted. In the complete callback mcba_usb_read_bulk_callback(), the URBs are processed and resubmitted.
 In mcba_usb_close() -> mcba_urb_unlink() the URBs are freed by calling
 usb_kill_anchored_urbs(&priv->rx_submitted). However, this does not take into account that the USB
 framework unanchors the URB before the complete function is called. This means that once an in-URB has
 been completed, it is no longer anchored and is ultimately not released in usb_kill_anchored_urbs(). Fix
 the memory leak by anchoring the URB in the mcba_usb_read_bulk_callback()to the priv->rx_submitted anchor.
 (CVE-2026-23080)

Solution

Update the linux library and its related packages to version 6.1.162-1 or later.
