kernel: Count overflow in FUSE request leading to use-after-free issues.

A flaw was found in the Linux kernel's implementation of the FUSE filesystem, where it allows a page reference counter overflow. If a page reference counter overflows into a negative value, it can be placed back into the "free" list for reuse by other applications. This flaw allows a local attack...

EulerOS 2.0 SP8 : kernel (EulerOS-SA-2020-1807)

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - The kernel package contains the Linux kernel vmlinuz, the core of any Linux operating system. The kernel handles the basic functions of the...

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...

Amazon Linux AMI : kernel (ALAS-2020-1401)

The version of kernel installed on the remote host is prior to 4.14.186-110.268. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1401 advisory. An issue where a provided address with accessok is not checked was discovered in i915gemexecbuffer2ioctl in...

Linux ioperm bitmap context switching issues

ISSUE DESCRIPTION Linux 5.5 overhauled the internal state handling for the iopl and ioperm system calls. Unfortunately, one aspect on context switch wasn't wired up correctly for the Xen PVOps case. IMPACT IO port permissions don't get rescinded when context switching to an unprivileged task...

Important: kernel

Issue Overview: An issue where a provided address with accessok is not checked was discovered in i915gemexecbuffer2ioctl in drivers/gpu/drm/i915/i915gemexecbuffer.c in the Linux kernel through 4.19.13. A local attacker can craft a malicious IOCTL function call to overwrite arbitrary kernel memory...

ASB-A-135368228

In i915gemexecbuffer2ioctl of i915gemexecbuffer.c, there is a possible arbitrary kernel memory write due to a missing validation of a userspace pointer. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation...
