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...

Background MirageOS is a library operating system using cooperative multitasking, which can be executed as a guest of the Xen hypervisor. Virtual machines running on a Xen host can communicate by sharing pages of memory. For example, when a Mirage VM wants to use a virtual network device provided...

The vulnerability of Xen hypervisors arises from the unsafe combination of small IOMMUs with larger ones, allowing attackers to increase their privileges.
