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-2025-69649 [HIGH] CWE-476 binutils: NULL pointer dereference in readelf via crafted ELF binary with malformed header fields
binutils: NULL pointer dereference in readelf via crafted ELF binary with malformed header fields
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.
A flaw was found in binutils. Processing a specially crafted ELF binary file containing malformed header fields with the readelf program can trigger a NULL pointer dereference, causing a crash and resulting in a denial of service.
