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...

CVE-2021-42327

dplinksettingswrite in drivers/gpu/drm/amd/display/amdgpudm/amdgpudmdebugfs.c in the Linux kernel through 5.14.14 allows a heap-based buffer overflow by an attacker who can write a string to the AMD GPU display drivers debug filesystem. There are no checks on size within parsewritebufferintoparam...

CVE-2021-42327

CVE-2021-42327 is a Linux kernel heap-based buffer overflow in the AMDGPU display driver debugfs path (amdgpu_dm_debugfs.c). The flaw occurs in dp_link_settings_write where parse_write_buffer_into_params copies a userspace buffer into a 40-byte heap buffer without proper size checks against copy_...

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...
