Ubuntu Security Notice 6707-2 - Lonial Con discovered that the netfilter subsystem in the Linux kernel did not properly handle element deactivation in certain cases, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Notselwyn discovered that the netfilter subsystem in the Linux kernel did not properly handle verdict parameters in certain cases, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 6702-2 - It was discovered that the NVIDIA Tegra XUSB pad controller driver in the Linux kernel did not properly handle return values in certain error conditions. A local attacker could use this to cause a denial of service. It was discovered that the ARM Mali Display Processor driver implementation in the Linux kernel did not properly handle certain error conditions. A local attacker could possibly use this to cause a denial of service.

Ubuntu Security Notice 6706-1 - It was discovered that the Microchip USB Ethernet driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could use this to cause a denial of service.

Ubuntu Security Notice 6701-2 - Ruihan Li discovered that the bluetooth subsystem in the Linux kernel did not properly perform permissions checks when handling HCI sockets. A physically proximate attacker could use this to cause a denial of service. It was discovered that the NVIDIA Tegra XUSB pad controller driver in the Linux kernel did not properly handle return values in certain error conditions. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 6705-1 - It was discovered that the DesignWare USB3 for Qualcomm SoCs driver in the Linux kernel did not properly handle certain error conditions during device registration. A local attacker could possibly use this to cause a denial of service. It was discovered that the NVIDIA Tegra XUSB pad controller driver in the Linux kernel did not properly handle return values in certain error conditions. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 6704-1 - It was discovered that the NVIDIA Tegra XUSB pad controller driver in the Linux kernel did not properly handle return values in certain error conditions. A local attacker could use this to cause a denial of service. Quentin Minster discovered that the KSMBD implementation in the Linux kernel did not properly handle session setup requests. A remote attacker could possibly use this to cause a denial of service.

Ubuntu Security Notice 6686-4 - It was discovered that the DesignWare USB3 for Qualcomm SoCs driver in the Linux kernel did not properly handle certain error conditions during device registration. A local attacker could possibly use this to cause a denial of service. It was discovered that a race condition existed in the Cypress touchscreen driver in the Linux kernel during device removal, leading to a use-after- free vulnerability. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code.

Lektor Static CMS version 3.3.10 suffers from an arbitrary file upload vulnerability that can be leveraged to achieve remote code execution.
