CVE-2026-97876 (GCVE-0-2026-97876)

Title
Bypass of GRUB lockdown restriction in Secure Boot mode via serial command MMIO base address
Summary
A local attacker with control over GRUB's configuration can bypass lockdown restrictions when booting with Secure Boot and load an unsigned GRUB module, while GRUB continues to report lockdown is enabled.
The vulnerability is caused by insufficient validation of the MMIO base address passed to the GRUB serial command. GRUB does not validate that the base address corresponds to a UART device, rather than being an arbitrary memory address. This allows an attacker to trick GRUB into writing non-arbitrary data at an attacker-controlled address, including resetting the grub_file_verifiers list in a way that disables the subsequent verification of loaded modules.

Title
GNU libextractor before 1.16 Privilege Escalation via LIBEXTRACTOR_PREFIX
Summary
GNU libextractor before 1.16 loads plugins from an untrusted search path specified by the LIBEXTRACTOR_PREFIX environment variable without proper privilege checks. A local attacker can exploit this by setting LIBEXTRACTOR_PREFIX to a directory containing a malicious plugin that executes arbitrary code with elevated privileges when loaded by a setuid or setgid program.

Title
GNU Binutils Dynamic Relocation Allocation elfxx-x86.c elf_x86_allocate_dynrelocs null pointer dereference
Summary
A vulnerability was detected in GNU Binutils 2.47. Affected by this vulnerability is the function elf_x86_allocate_dynrelocs of the file bfd/elfxx-x86.c of the component Dynamic Relocation Allocation. The manipulation results in null pointer dereference. The attack requires a local approach. The exploit is now public and may be used. Upgrading to version 2.48 addresses this issue. The patch is identified as d1268210b6f6/471130b39c0/283d3198bed/0a84e560216/a692a633d40. Upgrading the affected component is recommended.

Title
GNU libextractor before 1.15 Stack Overflow via OLE2
Summary
GNU libextractor before 1.15 contains a stack-based buffer overflow vulnerability in the process_star_office function that sizes a variable-length stack array from attacker-controlled OLE2 stream data. Attackers can craft malicious StarOffice documents that allocate up to 4 MB on the stack, causing stack overflow and crashing any application extracting metadata from the document.

CVE-2026-97876 (GCVE-0-2026-97876)
Vulnerability from cvelistv5 – Published: 2026-10-02 10:34 – Updated: 2026-10-02 10:34

Title
Bypass of GRUB lockdown restriction in Secure Boot mode via serial command MMIO base address
Summary
A local attacker with control over GRUB's configuration can bypass lockdown restrictions when booting with Secure Boot and load an unsigned GRUB module, while GRUB continues to report lockdown is enabled.
The vulnerability is caused by insufficient validation of the MMIO base address passed to the GRUB serial command. GRUB does not validate that the base address corresponds to a UART device, rather than being an arbitrary memory address. This allows an attacker to trick GRUB into writing non-arbitrary data at an attacker-controlled address, including resetting the grub_file_verifiers list in a way that disables the subsequent verification of loaded modules.
Severity
6.4 (Medium)

Title
GNU libextractor before 1.16 Privilege Escalation via LIBEXTRACTOR_PREFIX
Summary
GNU libextractor before 1.16 loads plugins from an untrusted search path specified by the LIBEXTRACTOR_PREFIX environment variable without proper privilege checks. A local attacker can exploit this by setting LIBEXTRACTOR_PREFIX to a directory containing a malicious plugin that executes arbitrary code with elevated privileges when loaded by a setuid or setgid program.

Title
GNU libextractor before 1.15 Stack Overflow via OLE2
Summary
GNU libextractor before 1.15 contains a stack-based buffer overflow vulnerability in the process_star_office function that sizes a variable-length stack array from attacker-controlled OLE2 stream data. Attackers can craft malicious StarOffice documents that allocate up to 4 MB on the stack, causing stack overflow and crashing any application extracting metadata from the document.

Title
GNU Binutils Eh Frame Section elf-eh-frame.c _bfd_elf_write_section_eh_frame buffer overflow
Summary
A vulnerability was detected in GNU Binutils 2.47. Affected by this issue is the function _bfd_elf_write_section_eh_frame of the file bfd/elf-eh-frame.c of the component Eh Frame Section Handler. Performing a manipulation of the argument cie_length/fde_length/augmentation_data_size/write_offset results in buffer overflow. Attacking locally is a requirement. The exploit is now public and may be used. The project was informed of the problem early through a bug report but has not responded yet.
