CVE ID         : CVE-2026-35535
Debian Bug     : 1130593

Qualys released an advisory called CrackArmor reporting that in sudo, an
application that provide limited super user privileges to specific users, a
failure during a privilege drop before running the mailer is not a fatal error,
which could lead to privilege escalation.

For Debian 11 bullseye, this problem has been fixed in version
1.9.5p2-3+deb11u4.

We recommend that you upgrade your sudo packages.

For the detailed security status of sudo please refer to
