Echo: linux: security update to 6.1.170-1

medium Tenable Cloud Security Plugin ID 464422

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: bcm: fix locking for bcm_op
runtime updates Commit c2aba69d0c36 ("can: bcm: add locking for bcm_op runtime updates") added a locking
for some variables that can be modified at runtime when updating the sending bcm_op with a new TX_SETUP
command in bcm_tx_setup(). Usually the RX_SETUP only handles and filters incoming traffic with one
exception: When the RX_RTR_FRAME flag is set a predefined CAN frame is sent when a specific RTR frame is
received. Therefore the rx bcm_op uses bcm_can_tx() which uses the bcm_tx_lock that was only initialized
in bcm_tx_setup(). Add the missing spin_lock_init() when allocating the bcm_op in bcm_rx_setup() to handle
the RTR case properly. (CVE-2026-23362)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
