Echo: linux: security update to 6.1.187-1

medium Tenable Self-Hosted Container Security Plugin ID 458839

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: mptcp: pm: ADD_ADDR rtx: free sk if
 last When an ADD_ADDR is retransmitted, the sk is held in sk_reset_timer(), and released at the end. If at
 that moment, it was the last reference being held, the sk would not be freed. sock_put() should then be
 called instead of __sock_put(). But that's not enough: if it is the last reference, sock_put() will call
 sk_free(), which will end up calling sk_stop_timer_sync() on the same timer, and waiting indefinitely to
 finish. So it is needed to mark that the timer is done at the end of the timer handler when it has not
 been rescheduled, not to call sk_stop_timer_sync() on "itself". (CVE-2026-46170)

Solution

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