Echo: linux: security update to 6.1.153-1

high Tenable Self-Hosted Container Security Plugin ID 464044

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: xilinx_can: xcan_write_frame():
 fix use-after-free of transmitted SKB can_put_echo_skb() takes ownership of the SKB and it may be freed
 during or after the call. However, xilinx_can xcan_write_frame() keeps using SKB after the call. Fix that
 by only calling can_put_echo_skb() after the code is done touching the SKB. The tx_lock is held for the
 entire xcan_write_frame() execution and also on the can_get_echo_skb() side so the order of operations
 does not matter. An earlier fix commit 3d3c817c3a40 ("can: xilinx_can: Fix usage of skb memory") did not
 move the can_put_echo_skb() call far enough. [mkl: add "commit" in front of sha1 in patch description]
 [mkl: fix indention] (CVE-2025-39873)
