CVE-2024-50115

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Ignore nCR34:0 when loading PDPTEs from memory Ignore nCR34:0 when loading PDPTEs from memory for nested SVM, as bits 4:0 of CR3 are ignored when PAE paging is used, and thus VMRUN doesn't enforce 32-byte alignment of...

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...

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...
