CVE-2025-4802

A flaw was found in the glibc library. A statically linked setuid binary that calls dlopen(), including internal dlopen() calls after setlocale() or calls to NSS functions such as getaddrinfo(), may incorrectly search LD_LIBRARY_PATH to determine which library to load, allowing a local attacker to load malicious shared libraries, escalate privileges and execute arbitrary code.

This issue can only be exploitable by a local attacker via a static setuid program that calls the dlopen function, causing the library to search LD_LIBRARY_PATH to locate the shared object name to load. No such programs have been found in Red Hat Enterprise Linux at the time of publishing this advisory. However, custom setuid programs, although strongly discouraged as a security practice, may exist and can not be discarded. Due to these reasons, this flaw has been rated with a moderate severity.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
