Hi,

The following vulnerability was published for glibc.

CVE-2025-8058[0]:
| The regcomp function in the GNU C library version from 2.4 to 2.41
| 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.


If you fix the vulnerability please also make sure to include the
