Astra Linux – Vulnerability in Linux

A flaw was discovered in the KVM’s AMD code, responsible for supporting SVM nested virtualization. The flaw occurs during the processing of the VMCB virtual machine control block provided by the L1 guest, which is used to spawn or handle a nested guest L2. Due to improper validation of the “intct...

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...
