kernel: Infoleak caused by incorrect handling of the SG_IO ioctl

A malformed SGIO ioctl issued for a SCSI device in the Linux kernel leads to a local kernel data leak manifesting in up to approximately 1000 memory pages copied to the userspace. The problem has limited scope as non-privileged users usually have no permissions to access SCSI device files...

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...

Apple iOSmacOS - Kernel Memory Corruption due to Integer Overflow in IOHIDResourceQueue::enqueueReport

Apple iOSmacOS - Kernel Memory Corruption due to Integer Overflow in IOHIDResourceQueue::enqueueReport / IOHIDResourceQueue inherits from IOSharedDataQueue and adds its own ::enqueueReport method, which seems to be mostly copy-pasted from IOSharedDataQueue and IODataQueue's ::enqueue methods. I...

DEBIAN-CVE-2018-18021

arch/arm64/kvm/guest.c in KVM in the Linux kernel before 4.18.12 on the arm64 platform mishandles the KVMSETONREG ioctl. This is exploitable by attackers who can create virtual machines. An attacker can arbitrarily redirect the hypervisor flow of control with full register control. An attacker ca...
