kernel: SVM nested virtualization issue in KVM (VMLOAD/VMSAVE)

A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB virtual machine control block provided by the L1 guest to spawn/handle a nested guest L2. Due to improper validation of the "virtext" field, this issue could allow a malicious...

USN-5120-1: Linux kernel (Azure) vulnerabilities

It was discovered that the f2fs file system in the Linux kernel did not properly validate metadata in some situations. An attacker could use this to construct a malicious f2fs image that, when mounted and operated on, could cause a denial of service system crash or possibly execute arbitrary code...

Linux kernel 缓冲区错误漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel versions prior to 5.14.14, which originates from a heap-based buffer overflow in the dplinksettingswrite of the...

The vulnerability of AMD’s microprogrammed software for processors lies in the speculative execution of read and write operations that access memory using invalid non- canonical addresses. This allows a hacker to exploit the vulnerability to gain access to information about the CPU’s address space.

The vulnerability of AMD’s microprogramming software is related to speculative operations for reading and writing data to memory, involving the use of non- canonical addresses. Exploiting this vulnerability can allow an attacker to gain access to information about the CPU’s address space, by usin...
