Echo: linux: security update to 6.1.176-1

critical Tenable Self-Hosted Container Security Plugin ID 465684

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: Fix slab-out-of-bounds access
 in auth message processing If a (potentially corrupted) message of type CEPH_MSG_AUTH_REPLY contains a
 positive value in its result field, it is treated as an error code by ceph_handle_auth_reply() and
 returned to handle_auth_reply(). Thereafter, an attempt is made to send the preallocated message of type
 CEPH_MSG_AUTH, where the returned value is interpreted as the size of the front segment to send. If the
 result value in the message is greater than the size of the memory buffer allocated for the front segment,
 an out-of-bounds access occurs, and the content of the memory region beyond this buffer is sent out. This
 patch fixes the issue by treating only negative values in the result field as errors. Positive values are
 therefore treated as success in the same way as a zero value. Additionally, a BUG_ON is added to
 __send_prepared_auth_request() comparing the len parameter to front_alloc_len to prevent sending the
 message if it exceeds the bounds of the allocation and to make it easier to catch any logic flaws leading
 to this. (CVE-2026-46119)

Solution

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