CVE-2026-18871 (GCVE-0-2026-18871)

Vulnerability from cvelistv5 – Published: 2026-08-19 19:36 – Updated: 2026-08-20 15:57

Title

Power System Buffer Overflow

Summary

IBM PowerVM Hypervisor FW1120.00, FW1110.00 through FW1110.30, and FW1060.00 through FW1060.80 is affected by a vulnerability in host firmware configuration parsing. An attacker with authenticated service-level access to the service processor can write specially crafted configuration data, causing the host firmware boot stack to crash with possible memory corruption during system initialisation, resulting in an integrity and availability impact to the managed system.

Severity

7.3 (High)

CVE-2026-18303 (GCVE-0-2026-18303)

Vulnerability from cvelistv5 – Published: 2026-08-20 16:23 – Updated: 2026-08-27 16:24

Title

GIMP TIF File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability

Summary

GIMP TIF File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of TIF files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29399.

Severity

7.8 (High)

CVE-2026-18167 (GCVE-0-2026-18167)

Vulnerability from cvelistv5 – Published: 2026-09-03 22:24 – Updated: 2026-09-03 22:24

Title

Stack-based buffer overflow in TP-Link Archer AX55 v4

Summary

A stack-based buffer overflow vulnerability exists in the EasyMesh module of TP-Link Archer AX55 v4. When Mesh mode is enabled, a LAN attacker may submit crafted input that causes the easymesh daemon to crash and may potentially achieve remote code execution on the device. Successful exploitation may cause the EasyMesh daemon to crash and may potentially allow remote code execution when Mesh mode is enabled. This may result in high impact to the confidentiality, integrity, and availability of the affected device.

Severity

7.7 (High)

CVE-2026-17494 (GCVE-0-2026-17494)

Vulnerability from cvelistv5 – Published: 2026-08-19 18:42 – Updated: 2026-08-22 03:56

Title

Power System Buffer Overflow

Summary

IBM Power Systems Firmware FW1120.00, and FW1110.00 through FW1110.30 is affected by a vulnerability in the interface between the BMC and the host system. An attacker with service access to the BMC can send a specially crafted command, allowing arbitrary code to be executed on the host system, giving full control over the host system and all hosted partitions, resulting in a confidentiality, integrity, and availability impact.

Severity

8.2 (High)

CVE-2026-17250 (GCVE-0-2026-17250)

Vulnerability from cvelistv5 – Published: 2026-08-21 17:16 – Updated: 2026-08-25 03:56

Title

Authenticated Remote Code Execution via Stack-Based Buffer Overflow in Firmware Update Handling

Summary

A stack-based buffer overflow vulnerability exists in the firmware update functionality of TL-MR6400 v7 due to unsafe processing of attacker-controlled metadata within a firmware image. Successful exploitation may allow an authenticated attacker to trigger memory corruption and execute arbitrary code on the affected device.

Severity

8.5 (High)
