Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 460894

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: libceph: Prevent potential null-ptr-
 deref in ceph_handle_auth_reply() If a message of type CEPH_MSG_AUTH_REPLY contains a zero value for both
 protocol and result, this is currently not treated as an error. In case of ac->negotiating == true and
 ac->protocol > 0, this leads to setting ac->protocol = 0 and ac->ops = NULL. Thereafter, the check for
 ac->protocol != protocol returns false, and init_protocol() is not called. Subsequently,
 ac->ops->handle_reply() is called, which leads to a null pointer dereference, because ac->ops is still
 NULL. This patch changes the check for ac->protocol != protocol to !ac->protocol, as this also includes
 the case when the protocol was set to zero in the message. This causes the message to be treated as
 containing a bad auth protocol. (CVE-2026-46024)

Solution

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