Echo: linux: security update to 6.3.7-1

high Tenable Cloud Security Plugin ID 458438

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: rxrpc: Make it so that a waiting
 process can be aborted When sendmsg() creates an rxrpc call, it queues it to wait for a connection and
 channel to be assigned and then waits before it can start shovelling data as the encrypted DATA packet
 content includes a summary of the connection parameters. However, sendmsg() may get interrupted before a
 connection gets assigned and further sendmsg() calls will fail with EBUSY until an assignment is made. Fix
 this so that the call can at least be aborted without failing on EBUSY. We have to be careful here as
 sendmsg() mustn't be allowed to start the call timer if the call doesn't yet have a connection assigned as
 an oops may follow shortly thereafter. (CVE-2023-53218)

Solution

Update the linux library and its related packages to version 6.3.7-1 or later.
