CVE-2018-7191

In the tun subsystem in the Linux kernel before 4.13.14, devgetvalidname is not called before registernetdevice. This allows local users to cause a denial of service NULL pointer dereference and panic via an ioctlTUNSETIFF call with a dev name containing a / character. This is similar to...

CVE-2018-7191

CVE-2018-7191 affects the Linux kernel tun subsystem prior to 4.13.14. Root cause: dev_get_valid_name is not called before register_netdevice, enabling a local user to trigger a NULL pointer dereference via ioctl(TUNSETIFF) with a device name containing a “/” character, potentially causing a deni...

Memory Corruption

Linux kernel is vulnerable to memory corruption vulnerability. This is because the ALSA sequencer core initializes the event pool on demand by invoking sndseqpoolinit when the first write happens and the pool is empty. A user can reset the pool size manually via ioctl concurrently causing an...

Privilege Escalation

Linux kernel is vulnerable to privilege escalation vulnerability. This occurs in the 32-bit compatibility layer of the ioctl handling code of the v4l2 video driver in the Linux kernel. An attacker to overwrite a kernel memory from an unprivileged userspace process causing a privilege escalation...

Improper Access Control

A flaw was found in the way the Linux kernel's floppy driver handled user space provided data in certain error code paths while processing FDRAWCMD IOCTL commands. A local user with write access to /dev/fdX could use this flaw to free using the kfree function arbitrary kernel memory...

CVE-2019-7303

A vulnerability in the seccomp filters of Canonical snapd before version 2.37.4 allows a strict mode snap to insert characters into a terminal on a 64-bit host. The seccomp rules were generated to match 64-bit ioctl2 commands on a 64-bit platform; however, the Linux kernel only uses the lower 32...

CVE-2019-7303

CVE-2019-7303 affects Canonical snapd before 2.37.4, where the seccomp filter for strict mode snaps could bypass input restrictions by allowing a 64-bit ioctl path (TIOCSTI) to insert characters into a terminal on a 64-bit host. The root cause is a mismatch: seccomp rules target 64-bit ioctl(2) c...

CVE-2019-7303 Snapd seccomp filter TIOCSTI ioctl bypass

A vulnerability in the seccomp filters of Canonical snapd before version 2.37.4 allows a strict mode snap to insert characters into a terminal on a 64-bit host. The seccomp rules were generated to match 64-bit ioctl2 commands on a 64-bit platform; however, the Linux kernel only uses the lower 32...

Kernel: KVM: potential use-after-free via kvm_ioctl_create_device()

A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor implements its device control API. While creating a device via kvmioctlcreatedevice, the device holds a reference to a VM object, later this reference is transferred to the caller's file descriptor table. If suc...
