This Red Hat security advisory addresses several vulnerabilities in GNU Binutils, specifically in the linker component's _bfd_elf_parse_eh_frame function, which can lead to heap-based buffer overflows (e.g., CVE-2025-11082). The update includes fixes for multiple CVEs affecting binutils packages for aarch64 and x86_64 architectures. Red Hat rates the impact as moderate because the affected binaries typically run with limited privileges in their default configurations. The advisory provides updated RPMs (version 2.46.1-1.hum1) to remediate these issues. No known exploits in the wild have been reported. Mitigations are limited or do not meet Red Hat's criteria for ease of use and applicability. The vulnerabilities involve weaknesses such as CWE-209 (information exposure), CWE-787 (out-of-bounds write), CWE-125 (out-of-bounds read), CWE-476 (null pointer dereference), and CWE-122 (heap-based buffer overflow).

The vulnerabilities can lead to heap-based buffer overflows and potential information disclosure when local users execute the affected binutils components. Due to default limited privileges, the overall impact is rated moderate by Red Hat. There are no reports of active exploitation in the wild. The flaws could potentially allow local attackers to cause crashes or execute arbitrary code with the privileges of the affected binaries, but the risk is mitigated by restricted execution contexts.

A security update is available and should be applied to affected systems. The update includes fixed versions of binutils packages (2.46.1-1.hum1) for aarch64 and x86_64 architectures. No effective mitigations other than applying the update are currently available or meet Red Hat's criteria for deployment. Users should follow Red Hat's official guidance and update their systems accordingly.
