CVE-2026-82474
HighCVSS 7.8Summary
Sudo through version 1.9.17p2 fails to apply intercept policy checks to the execveat system call in ptrace-based intercept mode. Users permitted to run specific commands can execute denied programs by calling execveat directly or through fexecve, bypassing policy enforcement and logging.
Risk Assessment
The risk involves the possibility of bypassing Sudo security policies, which could allow authorized users to run unauthorized programs with elevated privileges.
Recommendation
It is recommended to update Sudo to a version that properly handles the execveat system call in intercept mode, and to review policy configurations to ensure compliance.
Other vulnerabilities in Sudo
See all- CVE-2017-1000368High
Todd Miller's sudo version 1.8.20p1 and earlier is vulnerable to input validation (embedded newlines) in the get_process_ttyname() function resulting in information disclosure and command execution.
- CVE-2016-7032High
Sudo versions before 1.8.15 on Linux contain a vulnerability that may allow local users to bypass noexec command restrictions via applications calling the system or popen functions.
- CVE-2017-2381High
An issue was discovered in certain Apple products, including macOS before 10.12.4, related to the 'sudo' component. It allows remote authenticated users to gain privileges by leveraging membership in the admin group on a network directory server.
- CVE-2015-5602High
A vulnerability in sudoedit before version 1.8.15 allows local users to gain privileges via a symlink attack on a file whose full path is defined using multiple wildcards in /etc/sudoers.
- CVE-2026-35535High
In Sudo up to version 1.9.17p2 before commit 3e474c2, a failure of setuid, setgid, or setgroups calls during privilege drop before running the mailer is not a fatal error, which can lead to privilege escalation.
- CVE-2025-32462Low
A vulnerability in Sudo before version 1.9.17p1 allows listed users in the sudoers file to execute commands on unintended machines when the file specifies a host that is neither the current host nor ALL.
- CVE-1999-1496Low
Sudo version 1.5 on Debian Linux 2.1 and Red Hat 6.0 allows local users to determine the existence of arbitrary files by attempting to execute the target filename as a program, which generates different error messages when the file does not exist.
- CVE-1999-0958High
Sudo versions 1.5.x allow local users to execute arbitrary commands via a .. (dot dot) attack.
