CVE-2025-69651 GNU Binutils thru 2.46 readelf contains a vulnerability that leads to an invalid pointer free when processing a crafted ELF binary with malformed relocation or symbol data. If dump_relocations returns early due to parsing errors, the internal all_relocations array may remain partially uninitialized. Later, process_got_section_contents() may attempt to free an invalid r_symbol pointer, triggering memory corruption checks in glibc and causing the program to terminate with SIGABRT. No evidence of further memory corruption or code execution was observed; the impact is limited to denial of service.

CVE-2025-69649 GNU Binutils thru 2.46 readelf contains a null pointer dereference vulnerability when processing a crafted ELF binary with malformed header fields. During relocation processing, an invalid or null section pointer may be passed into display_relocations(), resulting in a segmentation fault (SIGSEGV) and abrupt termination. No evidence of memory corruption beyond the null pointer dereference, nor any possibility of code execution, was observed.

CVE-2025-69645 Binutils objdump contains a denial-of-service vulnerability when processing a crafted binary with malformed DWARF debug information. A logic error in the handling of DWARF compilation units can result in an invalid offset_size value being used inside byte_get_little_endian, leading to an abort (SIGABRT). The issue was observed in binutils 2.44. A local attacker can trigger the crash by supplying a malicious input file.

CVE-2025-69652 GNU Binutils thru 2.46 readelf contains a vulnerability that leads to an abort (SIGABRT) when processing a crafted ELF binary with malformed DWARF abbrev or debug information. Due to incomplete state cleanup in process_debug_info(), an invalid debug_info_p state may propagate into DWARF attribute parsing routines. When certain malformed attributes result in an unexpected data length of zero, byte_get_little_endian() triggers a fatal abort. No evidence of memory corruption or code execution was observed; the impact is limited to denial of service.

CVE-2025-69650 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.
