How to fix?

Upgrade Ubuntu:26.04 curl to version 8.18.0-1ubuntu2.8 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Ubuntu. See How to fix? for Ubuntu:26.04 relevant fixed versions and status.

When curl is built with GnuTLS, a malicious WebSocket server can make curl send memory past its send buffer. This is due to an out of bounds read following when gnutls_record_send() returns a number of bytes sent greater than the number of bytes it was given to send. GnuTLS does that after a blocked send.
