A security flaw has been discovered in GNU Binutils 2.47. This affects the function bfdelfehframesectionoffset of the file bfd/elf-eh-frame.c of the component Eh Frame Handler. Performing a manipulation results in null pointer dereference. The attack must be initiated from a local position. The...

CVE-2026-91779

GNU Binutils 2.47 is affected by a null pointer dereference in the function _bfd_elf_eh_frame_section_offset within the Eh Frame Handler component (bfd/elf-eh-frame.c). The flaw is exploitable via a local attack and primarily impacts availability (low severity, CVSS 3.1 base score 3.3). A proof-o...

CVE-2026-90831

A flaw was found in GNU Binutils. This vulnerability allows a local attacker to cause memory corruption by manipulating the ELF String Table component, specifically through the bfdelfstrtabdelref function. This could lead to unexpected behavior or system instability...

CVE-2026-90830

A flaw was found in GNU Binutils. This vulnerability, located in the bfdwritemergedsection function within the Section Merge component, allows a local attacker to trigger a null pointer dereference. This can lead to a denial of service DoS condition, making the affected system or application...

CVE-2026-90829

A flaw was found in GNU Binutils. A local attacker can exploit this vulnerability by manipulating the SHTGROUP Section. This manipulation can lead to a null pointer dereference within the bfdelfsetgroupcontents function. The primary consequence of this flaw is a denial of service...

CVE-2026-90828

A flaw was found in GNU Binutils. A local attacker, by performing a manipulation, can cause a null pointer dereference in the elforphancompatible function. This could lead to a denial of service or other unpredictable behavior...

CVE-2026-90804

A flaw was found in GNU Binutils. A buffer overflow vulnerability exists in the bfdelfwritesectionehframe function, part of the Eh Frame Section Handler. A local attacker can exploit this by providing specially crafted input that manipulates arguments such as cielength or fdelength. This...
