A flaw was found in the GNU Binutils (Binary Utilities) linker. This vulnerability, a heap-buffer-overflow read (CWE-125), occurs when the linker processes a specially crafted 32-bit XCOFF (Extended Common Object File Format) object file. An attacker could exploit this by providing a malicious file, leading to an out-of-bounds read of memory. This can result in information disclosure, potentially revealing sensitive heap data, and a Denial of Service (DoS) due to the linker crashing.

Threats
Impact
Moderate
A flaw was found in GNU Binutils. A buffer overflow vulnerability exists in the `cache_bwrite` function within the `bfd/cache.c` file of the `ld` component. This flaw can be triggered by manipulating the `nbytes` argument, allowing a local attacker to potentially cause information disclosure or denial of service.

CVE-2026-15003
Threats
Impact
Moderate
A flaw was found in GNU Binutils. A local attacker can exploit a null pointer dereference vulnerability in the `bfd_putl64` function of the `ld` component. This can lead to a denial of service or application instability.

Threats
Impact
Moderate
A flaw was found in GNU Binutils. A local attacker could exploit a buffer overflow vulnerability in the `elf_x86_64_relocate_section` function of the `ld` component by providing a malformed relocation. This could lead to potential information disclosure, data corruption, or denial of service.
6.6 (Medium)
Affected products
Fixed
9 products, the same list as for
CVE-2026-15003
Threats
Impact
Moderate
A flaw was found in GNU Binutils. A buffer overflow vulnerability exists in the _bfd_elf_write_section_eh_frame function, part of the Eh Frame Section Handler. A local attacker can exploit this by providing specially crafted input that manipulates arguments such as cie_length or fde_length. This manipulation can lead to a denial of service.

CVE-2026-15003
Threats
Impact
Moderate
A flaw was found in GNU Binutils. This vulnerability, located in the _bfd_write_merged_section 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 unavailable.
