Echo: linux: security update to 6.1.187-1

high Tenable Self-Hosted Container Security Plugin ID 461538

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: smc: Use __sk_dst_get() and
 dst_dev_rcu() in in smc_clc_prfx_set(). smc_clc_prfx_set() is called during connect() and not under RCU
 nor RTNL. Using sk_dst_get(sk)->dev could trigger UAF. Let's use __sk_dst_get() and dev_dst_rcu() under
 rcu_read_lock() after kernel_getsockname(). Note that the returned value of smc_clc_prfx_set() is not used
 in the caller. While at it, we change the 1st arg of smc_clc_prfx_set[46]_rcu() not to touch dst there.
 (CVE-2025-40139)

Solution

Update the linux library and its related packages to version 6.1.187-1 or later.
