high Tenable Cloud Security Plugin ID 459662

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: only handle RESPONSE during
 service challenge Only process RESPONSE packets while the service connection is still in
 RXRPC_CONN_SERVICE_CHALLENGING. Check that state under state_lock before running response verification and
 security initialization, then use a local secured flag to decide whether to queue the secured-connection
 work after the state transition. This keeps duplicate or late RESPONSE packets from re-running the setup
 path and removes the unlocked post-transition state test. (CVE-2026-31676)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
