kernel: Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks

A flaw was found in the Linux kernel’s KVM implementation, where improper handing of the VMIO|VMPFNMAP VMAs in KVM bypasses RO checks and leads to pages being freed while still accessible by the VMM and guest. This flaw allows users who can start and control a VM to read/write random pages of...

RHEL 7 : kernel (RHSA-2021:3725)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:3725 advisory. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: kernel: Improper handling of...

Important: kernel

Issue Overview: A flaw was found in the Linux kernel. When reusing a socket with an attached dccpshctxccid as a listener, the socket will be used after being released leading to denial of service DoS or a potential code execution. The highest threat from this vulnerability is to data...
