CVE-2023-46813

An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access to MMIO registers. Incorrect access checking in the VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses could lead to arbitrary write access to kernel memory and th...

SUSE CVE-2003-0699

The C-Media PCI sound driver in Linux before 2.4.21 does not use the getuser function to access userspace, which crosses security boundaries and may facilitate the exploitation of vulnerabilities, a different vulnerability than CVE-2003-0700...

SUSE CVE-2005-3276

The sysgetthreadarea function in process.c in Linux 2.6 before 2.6.12.4 and 2.6.13 does not clear a data structure before copying it to userspace, which might allow a user process to obtain sensitive information...

SUSE CVE-2014-5148

Xen 4.4.x, when running on an ARM system and "handling an unknown system register access from 64-bit userspace," returns to an instruction of the trap handler for kernel space faults instead of an instruction that is associated with faults in 64-bit userspace, which allows local guest users to...

SUSE CVE-2018-18021

arch/arm64/kvm/guest.c in KVM in the Linux kernel before 4.18.12 on the arm64 platform mishandles the KVMSETONREG ioctl. This is exploitable by attackers who can create virtual machines. An attacker can arbitrarily redirect the hypervisor flow of control with full register control. An attacker ca...

UBUNTU-CVE-2021-4159

A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating som...

CVE-2022-20239

remappfnrange' here may map out of size kernel memory for example, may map the kernel area, and because the 'vma-vmpageprot' can also be controlled by userspace, so userspace may map the kernel area to be writable, which is easy to be exploitedProduct: AndroidVersions: Android SoCAndroid ID:...

An issue was discovered in the Linux kernels Userspace Connection Manager Access for RDMA. This could allow a local attacker to crash the system, corrupt memory or escalate privileges...

Unspecified vulnerability in Linux kernel (CNVD-2021-24272)

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel 5.11.8 and earlier versions that allows userspace to write data directly to the kernel stack frame. No details of the...

DEBIAN-CVE-2021-28972

In drivers/pci/hotplug/rpadlparsysfs.c in the Linux kernel through 5.11.8, the RPA PCI Hotplug driver has a user-tolerable buffer overflow when writing a new device name to the driver from userspace, allowing userspace to write data to the kernel stack frame directly. This occurs because...

Kernel: vfio: access to disabled MMIO space of some devices may lead to DoS scenario

A flaw was found in the Linux kernel, where it allows userspace processes, for example, a guest VM, to directly access h/w devices via its VFIO driver modules. The VFIO modules allow users to enable or disable access to the devices' MMIO memory address spaces. If a user attempts to access the...

DEBIAN-CVE-2018-1000204

Linux Kernel version 3.18 to 4.16 incorrectly handles an SGIO ioctl on /dev/sg0 with dxferdirection=SGDXFERFROMDEV and an empty 6-byte cmdp. This may lead to copying up to 1000 kernel heap pages to the userspace. This has been fixed upstream in...
