Double Free

CVE-2025-8058

Medium
5.9/10

Summary

The "regcomp" function in the GNU C library version 2.4 through 2.41.9000 is subject to a double free if some previous allocation fails. It can be accomplished either by a malloc failure or by using an interposed malloc that injects random malloc failures. The double free can allow buffer manipulation depending of how the regex is constructed. This issue affects all architectures and ABIs supported by the GNU C library.
