                     CVE-2026-19177

    Security issues were discovered in Chromium which could result
    in the execution of arbitrary code, denial of service, or information
    disclosure.

    For the stable distribution (trixie), these problems have been fixed in
    version 151.0.7922.108-1~deb13u1.

    We recommend that you upgrade your chromium packages.

    For the detailed security status of chromium please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/chromium

    these updates to your system and frequently asked questions can be
