GNU Binutils Linker heap-based overflow
CVE: CVE-2025-11083
Component: binutils
CWE: CWE-787
Severity: Moderate
CVSS v3: 5.4/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L
Release date: 2025-09-27T23:02:08.428000+00:00

A head based buffer overflow flaw has been discovered in GNU bin utilities. The affected element is the function elf_swap_shdr in the library bfd/elfcode.h of the component Linker. The manipulation leads to heap-based buffer overflow. The attack must be carried out locally.

Statement: Red Hat rates this vulnerability as Moderate as a result of how the GNU Binutils are configured to be used in Red Hat products. When running with default configurations the affected program will have limited privileges and thus the impact of this flaw will be restricted.
