What to do

AI-suggested

For the libcurl vulnerability (CVE-2026-11856), the recommended mitigation is to avoid reusing the same libcurl easy handle for transfers to different HTTP origins when Digest authentication is used. Instead, create a fresh handle for each origin or explicitly clear authentication-related state before reuse. The vulnerability is fixed in libcurl version 8.21.0, so upgrading to this version or later resolves the issue.

A security advisory from Red Hat addresses multiple vulnerabilities in Red Hat AI Base Images 3.0.9 (CUDA), including CVE-2026-11856, a moderate-severity flaw in libcurl. This libcurl vulnerability involves incorrect reuse of Digest authentication headers across different HTTP origins, potentially exposing authenticated state information. The advisory notes no fixes currently available for the AI Base Images 3.0.9 (CUDA). The libcurl flaw is fixed in version 8.21.0, affecting versions 7.10.6 through 8.20.0. No known exploits in the wild have been reported. The advisory emphasizes correct usage patterns as mitigation for the libcurl issue.
