GHSA-4JQ9-2XHW-JPX7 Java: DoS Vulnerability in JSON-JAVA

Summary A denial of service vulnerability in JSON-Java was discovered by ClusterFuzz. A bug in the parser means that an input string of modest size can lead to indefinite amounts of memory being used. There are two issues: 1 the parser bug can be used to circumvent a check that is supposed to...

CVE-2023-20566

Improper address validation in ASP with SNP enabled may potentially allow an attacker to compromise guest memory integrity...

CVE-2022-23830

SMM configuration may not be immutable, as intended, when SNP is enabled resulting in a potential limited loss of guest memory integrity...

kernel: KVM: x86/mmu: race condition in direct_page_fault()

A flaw was found in the Linux kernel in the KVM. A race condition in directpagefault allows guest OS users to cause a denial of service host OS crash or host OS memory corruption when nested virtualization and the TDP MMU are enabled...

kernel: KVM: nVMX: missing consistency checks for CR0 and CR4

A flaw was found in the KVM's Intel nested virtualization feature nVMX. The effective values of the guest CR0 and CR4 registers could differ from those included in the VMCS12. In rare circumstances i.e., kvmintel module loaded with parameters nested=1 and ept=0 this could allow a malicious guest ...
