CVE-2024-50115

CVE-2024-50115 is a Linux kernel vulnerability affecting KVM nSVM where loading PDPTEs from memory incorrectly handles nCR3[4:0]. The issue can cause an out-of-bounds read if a target page is at the end of a memslot, due to not enforcing 32-byte alignment when PAE paging is used. The root cause i...

PT-2024-33948

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.6.61 Description: The issue is related to the KVM: nSVM flow in the Linux kernel, where bits 4:0 of CR3 are not ignored when loading PDPTEs from memory for nested SVM. This can result in an out-of-bounds read ...

CVE-2022-48793

A vulnerability was found in the nested.c file in the Linux kernel's KVM driver, where a potential NULL dereference can occur. This happens when the call to load the nested state is executed before Nested Page Tables NPT are enabled, preventing access to guest memory, lead to system instability a...
