CVE-2025-32463 – Sudo chroot 1.9.17 - Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2025-32463
30 Jun 2025 — Sudo before 1.9.17p1 allows local users to obtain root access because /etc/nsswitch.conf from a user-controlled directory is used with the --chroot option. A flaw was found in Sudo. This flaw allows a local attacker to escalate their privileges by tricking Sudo into loading an arbitrary shared library using the user-specified root directory via the `-R` (`--chroot`) option. An attacker can run arbitrary commands as root on systems that support `/etc/nsswitch.conf`. Rich Mirch discovered that Sudo incorrectl... • https://packetstorm.news/files/id/206210 • CWE-427: Uncontrolled Search Path Element CWE-829: Inclusion of Functionality from Untrusted Control Sphere •

https://notcve.org/view.php?id=CVE-2025-6018
18 Jun 2025 — A Local Privilege Escalation (LPE) vulnerability has been discovered in pam-config within Linux Pluggable Authentication Modules (PAM). This flaw allows an unprivileged local attacker (for example, a user logged in via SSH) to obtain the elevated privileges normally reserved for a physically present, "allow_active" user. The highest risk is that the attacker can then perform all allow_active yes Polkit actions, which are typically restricted to console users, potentially gaining unauthorized control over sy... • https://packetstorm.news/files/id/207433 • CWE-863: Incorrect Authorization •
