CVE-2026-35535
Description
A flaw was found in Sudo. A local user could exploit a failure in the setuid, setgid, or setgroups calls, which are used to drop privileges before running the mailer. This oversight allows for privilege escalation, enabling the user to gain elevated access on the system.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Access Control,Confidentiality
Technical Impact: Gain Privileges or Assume Identity; Read Application Data; Read Files or Directories
An attacker may be able to access resources with the elevated privilege that could not be accessed with the attacker's original privileges. This is particularly likely in conjunction with another flaw, such as a buffer overflow.
