Linux kernel vhost 'vhost/vhost.c:vhost_new_msg()' function denial of service vulnerability
The Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. vhost is one of the drivers that provides kernel virtio device emulation. A security vulnerability exists in the 'vhost/vhost.c:vhostnewmsg' function of vhost in...
hw: cpu: speculative execution permission faults handling
An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions a commonly used performance optimization. There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant...
Linux kernel 'cdrom_ioctl_media_changed' function denial of service vulnerability
Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A security vulnerability exists in the 'cdromioctlmediachanged' function in the drivers/cdrom/cdrom.c file in Linux kernel versions prior to 4.16.6. A local attacker c...
CVE-2018-1118
Linux kernel vhost since version 4.8 does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhostnewmsg function. This can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-ne...

kernel: Out-of-bounds write via userland offsets in ebt_entry struct in netfilter/ebtables.c
A flaw was found in the Linux kernel's implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory...

kernel: v4l2: disabled memory access protection mechanism allowing privilege escalation
A bug in the 32-bit compatibility layer of the ioctl handling code of the v4l2 video driver in the Linux kernel has been found. A memory protection mechanism ensuring that user-provided buffers always point to a userspace memory were disabled, allowing destination address to be in a kernel space...
