high Nessus Plugin ID 376501
Synopsis
The Rocky Linux host is missing one or more security updates.Description
The Rocky Linux 9.6 host has a package installed that is affected by a vulnerability as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1793885412 advisory.- Multiple ECH outer extension references are not permitted under RFC 9849; previously, a client could send a well-crafted packet that could trigger memory exhaustion in the server process by specifying multiple references. We now reject these as malformed and curb the memory amplification vector as a result.
(CVE-2026-97031)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
