Oracle Linux: CVE-2025-8058: ELSA-2025-12748: glibc security update (MODERATE) (Multiple Advisories)

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.
A double-free vulnerability has been discovered in glibc (GNU C Library). This flaw occurs during bracket expression parsing within the regcomp function, specifically when a memory allocation failure takes place. Exploitation of a double-free vulnerability can lead to memory corruption, which could enable an attacker to achieve arbitrary code execution or a denial of service condition.
