Imagination Graphics DDK 安全漏洞

Imagination Graphics DDK is a suite of GPU driver tools from Imagination UK. A security vulnerability exists in Imagination Graphics DDK, which stems from a possible information disclosure due to kernel software running in an untrusted environment...

The vulnerability of the verity_ctr() function in the drivers/md/dm-verity-target.c module of the device-mapper subsystem in the Linux operating system allows a attacker to execute arbitrary code and connect vulnerable hardware devices.

The vulnerability of the verityctr function in the drivers/md/dm-verity-target.c file of the device-mapper subsystem in the Linux operating system is related to the lack of verification for the types of tables that are loaded. Exploiting this vulnerability allows an attacker with administrative...

QEMU: loader: OOB access while loading registered ROM may lead to code execution

An out-of-bound write access flaw was found in the way QEMU loads ROM contents at boot time. This flaw occurs in the romcopy routine while loading the contents of a 32-bit -kernel image into memory. Running an untrusted -kernel image may load contents at arbitrary memory locations, potentially...

CVE-2020-24637

Two vulnerabilities in ArubaOS GRUB2 implementation allows for an attacker to bypass secureboot. Successful exploitation of this vulnerability this could lead to remote compromise of system integrity by allowing an attacker to load an untrusted or modified kernel in Aruba 9000 Gateway; Aruba 7000...

VulnCheck KEV: CVE-2020-10713

A flaw was found in grub2, prior to version 2.06. An attacker may use the GRUB 2 flaw to hijack and tamper the GRUB verification process. This flaw also allows the bypass of Secure Boot protections. In order to load an untrusted or modified kernel, an attacker would first need to establish access...

paravirtualised kernel image validation

ISSUE DESCRIPTION 1. Problems ----------- The functions which interpret the kernel image supplied for a paravirtualised guest, and decompress it into memory when booting the domain, are incautious. Specifically: i Integer overflow in the decompression loop memory allocator might result in...
