Ubuntu explains curl patch coverage: check both command-line tools and embedded libcurl
Ubuntu announces patches for several curl and libcurl vulnerabilities, noting that among Ubuntu releases, CVE-2026-92392 affects only 26.04 LTS. An identical tool name does not mean the affected conditions are identical across OS versions.

Source Facts
Canonical explained on 14 October that curl coordinated disclosure of several security issues that day, and that Ubuntu had provided related updates through USN-8927-1 and USN-8932-1. Both the curl command-line tool and the libcurl library used by applications are affected.
The article says that among the Ubuntu releases it lists, CVE-2026-92392 affects only 26.04 LTS; exploitation also requires a malicious server and specific conditions. Other issues concern particular uses of certificates, protocols or libraries, so assess them against versions and actual functions.
Alongside central package updates, identify applications that bundle libcurl. A single curl version query may miss separate copies.
