    Package        : mesa
    Version        : 20.3.5-1+deb11u1 $bookworm_VERSION
    CVE ID         : CVE-2026-40393
    Debian Bug     :

    A vulnerability has been found in the mesa 3D graphics library, possibly
    allowing out of bound memory access by craftet input.

    CVE-2026-40393

      An out-of-bounds memory access can occur in WebGPU because the amount
      of to-be-allocated data depends on an untrusted party, and is then
      used for alloca.

    For Debian 11 bullseye, this problem has been fixed in version
    20.3.5-1+deb11u1.

    For Debian 12 bookworm, this problem has been fixed in version
    $bookworm_VERSION.

    We recommend that you upgrade your mesa packages.

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