Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-4802 involves an untrusted LD_LIBRARY_PATH environment variable vulnerability found in the GNU C Library (glibc) versions 2.27 to 2.38. This vulnerability allows an attacker to control the loading of dynamically shared libraries. Specifically, the issue affects statically compiled setuid binaries that call dlopen, including internal dlopen calls made after setlocale or calls to NSS functions like getaddrinfo. An attacker could potentially exploit this to execute arbitrary code or escalate privileges by manipulating the library path in setuid binaries.
