CVE-2022-29223

Azure RTOS USBX is a USB host, device, and on-the-go OTG embedded stack. In versions prior to 6.1.10, an attacker can cause a buffer overflow by providing the Azure RTOS USBX host stack a HUB descriptor with "bNbPorts" set to a value greater than "UXMAXTT" which defaults to 8. For a "bNbPorts"...

CVE-2022-29223

Azure RTOS USBX contains a buffer overflow vulnerability in the USB host stack when processing a HUB descriptor with bNbPorts greater than UX_MAX_TT (default 8) in versions prior to 6.1.10. In particular, a HUB descriptor with bNbPorts = 255 can cause ux_host_class_hub_descriptor_get to write bey...

CVE-2022-29223 Buffer overflow on HUB descriptor in Azure RTOS USBX

Azure RTOS USBX is a USB host, device, and on-the-go OTG embedded stack. In versions prior to 6.1.10, an attacker can cause a buffer overflow by providing the Azure RTOS USBX host stack a HUB descriptor with bNbPorts set to a value greater than UXMAXTT which defaults to 8. For a bNbPorts value of...

PT-2022-19475

Name of the Vulnerable Software and Affected Versions Azure RTOS USBX versions prior to 6.1.10 Description The issue arises when an attacker provides a HUB descriptor with bNbPorts set to a value greater than UX MAX TT, which defaults to 8, causing a buffer overflow in the Azure RTOS USBX host...

Microsoft Azure RTOS USBX security vulnerability

Microsoft Azure RTOS USBX is a high-performance USB host, device, and mobile OTG embedded stack open-sourced by Microsoft in the United States and fully integrated with Azure RTOS ThreadX. A security vulnerability exists in Microsoft Azure RTOS USBX versions prior to 6.1.10. An attacker exploits...

Kernel: ppc: kvm: conflicting use of HSTATE_HOST_R1 to store r1 state leads to host stack corruption

A flaw was found in the way the KVM hypervisor on the Power8 processor stores the r1 register state in the 'HSTATEHOSTR1' field on the Linux kernel stack. This flaw occurs while handling hypercalls in Transactional Memory TM suspend mode in the kvmppcsavetm and kvmppcrestoretm routines, leading t...

DEBIAN-CVE-2020-8834

KVM in the Linux kernel on Power8 processors has a conflicting use of HSTATEHOSTR1 to store r1 state in kvmppchventry plus in kvmppcsave,restoretm, leading to a stack corruption. Because of this, an attacker with the ability run code in kernel space of a guest VM can cause the host kernel to pani...

Kernel: KVM: leak of uninitialized stack contents to guest

An information leakage issue was found in the way Linux kernel's KVM hypervisor handled page fault exceptions while emulating instructions like VMXON, VMCLEAR, VMPTRLD, and VMWRITE with memory address as an operand. It occurs if the operand is a mmio address, as the returned exception object hold...

Information Disclosure

QEMU is vulnerable to information disclosure attacks. This is because the patchinstruction function in hw/i386/kvmvapic.c does not initialize the imm32 variable which allows a local attacker to obtain sensitive information from host stack memory by accessing the Task Priority Register TPR...

CVE-2016-9932: Exposure of Sensitive Information to an Unauthorized Actor

CMPXCHG8B emulation in Xen 3.3.x through 4.7.x on x86 systems allows local HVM guest OS users to obtain sensitive information from host stack memory via a "supposedly-ignored" operand size prefix...
