Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 463263

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: nvmet-tcp: propagate
 nvmet_tcp_build_pdu_iovec() errors to its callers Currently, when nvmet_tcp_build_pdu_iovec() detects an
 out-of-bounds PDU length or offset, it triggers nvmet_tcp_fatal_error(cmd->queue) and returns early.
 However, because the function returns void, the callers are entirely unaware that a fatal error has
 occurred and that the cmd->recv_msg.msg_iter was left uninitialized. Callers such as
 nvmet_tcp_handle_h2c_data_pdu() proceed to blindly overwrite the queue state with queue->rcv_state =
 NVMET_TCP_RECV_DATA Consequently, the socket receiving loop may attempt to read incoming network data into
 the uninitialized iterator. Fix this by shifting the error handling responsibility to the callers.
 (CVE-2026-52989)

Solution

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