Echo: linux: security update to 6.1.159-1

medium Tenable Cloud Security Plugin ID 458479

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: kvaser_usb: leaf: Fix potential
 infinite loop in command parsers The `kvaser_usb_leaf_wait_cmd()` and `kvaser_usb_leaf_read_bulk_callback`
 functions contain logic to zero-length commands. These commands are used to align data to the USB
 endpoint's wMaxPacketSize boundary. The driver attempts to skip these placeholders by aligning the buffer
 position `pos` to the next packet boundary using `round_up()` function. However, if zero-length command is
 found exactly on a packet boundary (i.e., `pos` is a multiple of wMaxPacketSize, including 0), `round_up`
 function will return the unchanged value of `pos`. This prevents `pos` to be increased, causing an
 infinite loop in the parsing logic. This patch fixes this in the function by using `pos + 1` instead. This
 ensures that even if `pos` is on a boundary, the calculation is based on `pos + 1`, forcing `round_up()`
 to always return the next aligned boundary. (CVE-2025-68308)

Solution

Update the linux library and its related packages to version 6.1.159-1 or later.
