A missing bounds check in the image loader used in Blender 3.x and 2.93.8 leads to out-of-bounds heap access, allowing an attacker to cause denial of service, memory corruption, or potentially code execution...

Astra Linux – Vulnerability in Qemu

A out-of-bounds heap buffer access issue was identified in the ARM Generic Interrupt Controller emulator of QEMU, as of and including qemu 4.2.0 on the aarch64 platform. The issue arises because, when writing an interrupt ID to the controller’s memory area, it is not masked to be 4 bits wide. Thi...

CVE-2026-33642
