CVE-2025-69650
GNU Binutils Double Free Vulnerability
Description
GNU Binutils thru 2.46 readelf contains a double free vulnerability when processing a crafted ELF binary with malformed relocation data. During GOT relocation handling, dump_relocations may return early without initializing the all_relocations array. As a result, process_got_section_contents() may pass an uninitialized r_symbol pointer to free(), leading to a double free and terminating the program with SIGABRT. No evidence of exploitable memory corruption or code execution was observed; the impact is limited to denial of service. NOTE: this is disputed by third parties because the observed behavior occurred only in pre-release code and did not affect any tagged version.
