{agent} Docker images for {ecloud} have been reverted from having been based off of Ubuntu 24.04 to being based off of Ubuntu 20.04. This is to ensure compatibility with {ece}, support for new Wolfi-based images, and for GNU C Library (glibc) compatibility. #6393

{kib} out of memory crashes on 1 GB {ecloud} {kib} instances using {elastic-sec} view
Details
{ecloud} deployments that use the smallest available {kib} instance size of 1 GB may crash due to out of memory errors when the Security UI is loaded.
Impact
The root cause is inefficient memory allocation, and this is exacerbated when the prebuilt security rules package is installed on the initial load of the {elastic-sec} UI.

-
An {agent} with the Defend integration may report an Orphaned status and will not be able to be issued an upgrade action through {fleet}.
Details
A known issue in the {agent} may prevent it from being targetted with an upgrade action for a future release.
This may occur if the Defend integration is used and the agent is stopped on a running instance for too long.
An agent may be stopped as part of an upgrade process.
Impact
A bug fix is present in the 8.17.1 release of {fleet} that will prevent this from occuring.
If you have agents that are affected, the workaround is as follows:
# Get a Token to issue an update_by_query request:
curl -XPOST --user elastic:${SUPERUSER_PASS} -H 'x-elastic-product-origin:fleet' -H'content-type:application/json' "https://${ELASTICSEARCH_HOST}/_security/service/elastic/fleet-server/credential/token/fix-unenrolled"
# Issue an update_by_query request that targets effected agents:
curl -XPOST -H 'Authorization: Bearer ${TOKEN}' -H 'x-elastic-product-origin:fleet' -H 'content-type:application/json' "https://${ELASTICSEARCH_HOST}/.fleet-agents/_update_by_query" -d '{"query": {"bool": {"must": [{ "exists": { "field": "unenrolled_at" } }],"must_not": [{ "term": { "active": "false" } }]}},"script": {"source": "ctx._source.unenrolled_at = null;","lang": "painless"}}'
