Echo: linux: security update to 6.1.176-1

high Tenable Cloud Security Plugin ID 458355

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: nfc: llcp: add missing return after
 LLCP_CLOSED checks In nfc_llcp_recv_hdlc() and nfc_llcp_recv_disc(), when the socket state is LLCP_CLOSED,
 the code correctly calls release_sock() and nfc_llcp_sock_put() but fails to return. Execution falls
 through to the remainder of the function, which calls release_sock() and nfc_llcp_sock_put() again. This
 results in a double release_sock() and a refcount underflow via double nfc_llcp_sock_put(), leading to a
 use-after-free. Add the missing return statements after the LLCP_CLOSED branches in both functions to
 prevent the fall-through. (CVE-2026-31629)

Solution

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