Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 462902

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: net: rds: fix MR cleanup on copy error
 __rds_rdma_map() hands sg/pages ownership to the transport after get_mr() succeeds. If copying the
 generated cookie back to user space fails after that point, the error path must not free those resources
 again before dropping the MR reference. Remove the duplicate unpin/free from the put_user() failure branch
 so that MR teardown is handled only through the existing final cleanup path. (CVE-2026-46053)

Solution

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