EulerOS Virtualization 2.5.3 : kvm (EulerOS-SA-2019-1369)

According to the version of the kvm package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability : - An information leakage issue was found in the way Linux kernel's KVM hypervisor handled page fault exceptions while emulating instructio...

EulerOS Virtualization 2.5.3 : kvm (EulerOS-SA-2019-1370)

According to the version of the kvm package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability : - A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor emulates a preemption timer for L2 guests when...

Privilege Escalation

The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way Linux kernel's Transparent Huge Pages THP implementation handled non-huge page migration. A local, unprivileged user could use this flaw to crash the kernel by migrating transparent...

Denial Of Service (DoS)

The kernel packages contain the Linux kernel, the core of any Linux operating system. An integer overflow flaw was found in the way the Linux kernel's Frame Buffer device implementation mapped kernel memory to user space via the mmap syscall. A local user able to access a frame buffer device file...

Denial Of Service (DoS)

The kernel packages contain the Linux kernel, the core of any Linux operating system. It was found that the Linux kernel's Infiniband subsystem did not properly sanitize input parameters while registering memory regions from user space via the uverbs API. A local user with access to a...

Denial Of Service (DoS)

kernel is vulnerable to denial of service. A flaw was found in the way the xenfailsafecallback function in the Linux kernel handled the failed iret interrupt return instruction notification from the Xen hypervisor. An unprivileged user in a 32-bit para-virtualized guest could use this flaw to cra...

EulerOS 2.0 SP2 : kernel (EulerOS-SA-2019-1302)

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - A flaw was found in the Linux kernel's ext4 filesystem code. A use-after-free is possible in ext4extremovespace function when mounting and...

(Pwn2Own) Oracle VirtualBox e1000 Race Condition Privilege Escalation Vulnerability

This vulnerability allows local attackers to escalate privileges on vulnerable installations of Oracle VirtualBox.
