USN-3933-1: Linux kernel vulnerabilities

It was discovered that an information leak vulnerability existed in the Bluetooth implementation of the Linux kernel. An attacker within Bluetooth range could possibly expose sensitive information kernel memory. CVE-2017-1000410 It was discovered that the USB serial device driver in the Linux...

Walkthrough. Investigating an SSD

I had an interesting job come in. A client wants the data off a dead SSD, and it’s a model that regular data recovery companies won’t deal with, an SK Hynix drive. It’s used extensively on many Dell laptops. The drive is NVMe which means it uses several PCIe lanes for communication. First things...

CVE-2018-20785

Secure boot bypass and memory extraction can be achieved on Neato Botvac Connected 2.2.0 devices. During startup, the AM335x secure boot feature decrypts and executes firmware. Secure boot can be bypassed by starting with certain commands to the USB serial port. Although a power cycle occurs, thi...

CVE-2018-20785

CVE-2018-20785 affects Neato Botvac Connected 2.2.0. The AM335x secure boot can be bypassed by issuing certain commands to the USB serial port during startup, allowing execution of an unsigned QNX IFS image via a boot menu (XMODEM). A power cycle does not fully reset the chip, leaving memory cont...

Linux kernel denial of service vulnerability (CNVD-2019-38527)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A denial of service vulnerability exists in the changeportsettings file in drivers/usb/serial/ioti.c in Linux kernel versions prior to 4.11.3. A local attacker could...

Design/Logic Flaw

In changeportsettings in drivers/usb/serial/ioti.c in the Linux kernel before 4.11.3, local users could cause a denial of service by division-by-zero in the serial device layer by trying to set very high baud rates...

CVE-2017-18360

In changeportsettings in drivers/usb/serial/ioti.c in the Linux kernel before 4.11.3, local users could cause a denial of service by division-by-zero in the serial device layer by trying to set very high baud rates...

kernel: Division by zero in change_port_settings in drivers/usb/serial/io_ti.c resulting in a denial of service

A division-by-zero in settermios, when debugging is enabled, was found in the Linux kernel. When the ioti driver is loaded, a local unprivileged attacker can request incorrect high transfer speed in the changeportsettings in the drivers/usb/serial/ioti.c so that the divisor value becomes zero and...

USN-3583-1: Linux kernel vulnerabilities

It was discovered that an out-of-bounds write vulnerability existed in the Flash-Friendly File System f2fs in the Linux kernel. An attacker could construct a malicious file system that, when mounted, could cause a denial of service system crash or possibly execute arbitrary code. CVE-2017-0750 It...

Debian DLA-1200-1 : linux security update (KRACK)

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2016-10208 Sergej Schumilo and Ralf Spenneberg discovered that a crafted ext4 filesystem could trigger memory corruption when it is mounted. A user...

Ubuntu 17.10 : linux, linux-raspi2 vulnerabilities (USN-3487-1)

It was discovered that the KVM subsystem in the Linux kernel did not properly keep track of nested levels in guest page tables. A local attacker in a guest VM could use this to cause a denial of service host OS crash or possibly execute arbitrary code in the host OS. CVE-2017-12188 It was...

USN-3485-3 linux-aws vulnerabilities

It was discovered that a race condition existed in the ALSA subsystem of the Linux kernel when creating and deleting a port via ioctl. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2017-15265 Eric Biggers discovered that the key...
