Sudo

Local privilege escalation in Sudo through 1.9.17p2 (fixed in commit 3e474c2) arises because a failed setuid, setgid, or setgroups call during the privilege drop that precedes invoking the mailer is treated as non-fatal, allowing the mailer to run with retained elevated privileges. Local users on systems where Sudo is configured to send mail can leverage this to gain root, with total technical impact per CISA SSVC. EPSS is 0.00% and there is no public exploit identified at time of analysis, consistent with SSVC marking exploitation as none.

Sudo before 1.9.17p1 contains a local root escalation vulnerability (CVE-2025-32463, CVSS 9.3) through the --chroot option, which loads /etc/nsswitch.conf from the user-controlled chroot directory instead of the host system. KEV-listed with EPSS 26.5% and public PoC, this vulnerability allows any user with sudo --chroot access to achieve root privileges by placing a malicious nsswitch configuration and library in their chroot.

Sudo before 1.9.17p1, when used with a sudoers file that specifies a host that is neither the current host nor ALL, allows listed users to execute commands on unintended machines.
