CVE-2025-69650 is a vulnerability identified in GNU Binutils' readelf utility up to version 2.46. The flaw arises during the processing of ELF binaries containing malformed relocation data, particularly in the handling of Global Offset Table (GOT) relocations. The function dump_relocations may return prematurely without initializing the all_relocations array. Consequently, process_got_section_contents() may attempt to free an uninitialized r_symbol pointer, resulting in a double free error. This double free leads to the program terminating with a SIGABRT signal. Importantly, analysis has not revealed any exploitable memory corruption or potential for arbitrary code execution stemming from this vulnerability. The primary consequence is a denial of service condition where readelf crashes when parsing crafted ELF files. Since readelf is widely used for inspecting ELF binaries in Linux and Unix-like systems, this vulnerability could disrupt automated tooling, debugging, or build processes that rely on readelf. No patches or fixes have been linked yet, and no known exploits have been observed in the wild. The vulnerability was reserved in January 2026 and published in March 2026, indicating recent discovery. The lack of a CVSS score necessitates an independent severity assessment.

The main impact of CVE-2025-69650 is denial of service due to the crashing of the readelf utility when processing maliciously crafted ELF binaries. Organizations that rely on GNU Binutils for binary analysis, debugging, or build automation may experience interruptions or failures in their workflows. This can affect software development pipelines, continuous integration systems, and security analysis tools that parse ELF files. Although no code execution or data compromise has been demonstrated, denial of service can still have operational consequences, especially in environments that automatically process large volumes of ELF binaries. Attackers with the ability to supply or intercept ELF files could exploit this vulnerability to disrupt services or delay development processes. The lack of known exploits and the requirement to provide a crafted ELF file limit the scope somewhat, but the vulnerability remains a concern for organizations heavily dependent on GNU Binutils. The impact is primarily on availability, with no direct confidentiality or integrity risks identified.

To mitigate CVE-2025-69650, organizations should implement the following specific measures: 1) Avoid processing ELF binaries from untrusted or unauthenticated sources with readelf until a patch is available. 2) Monitor GNU Binutils project communications and security advisories for patches or updates addressing this vulnerability and apply them promptly. 3) Employ input validation or sandboxing techniques when handling ELF files to limit the impact of malformed binaries. 4) Integrate fallback or redundancy in build and analysis pipelines to handle potential readelf crashes gracefully, such as retry mechanisms or alternative tools. 5) Use file integrity monitoring to detect unexpected or suspicious ELF files entering critical systems. 6) Educate developers and system administrators about the vulnerability to increase awareness and encourage cautious handling of ELF files. These steps go beyond generic advice by focusing on controlling input sources, monitoring for updates, and ensuring operational resilience.
