Name of the Vulnerable Software and Affected Versions:

GNU C Library versions 2.4 through 2.41

Description:

The `regcomp` function is subject to a double free if a previous allocation fails. This can occur due to a `malloc` failure or through the use of an interposed `malloc` that introduces allocation failures. The double free can potentially allow buffer manipulation depending on the construction of the regular expression. This issue affects all supported architectures and ABIs.

Recommendations:

Versions prior to 2.41 are recommended.
