CVE-2021-30257

Possible out of bound read or write in VR service due to lack of validation of DSP selection values in Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT...

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...

kernel: SVM nested virtualization issue in KVM (AVIC support)

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 "intctl" field, this issue could allow a malicious ...
