CVE-2023-52490

The CVE-2023-52490 issue is a Linux kernel mm/migrate flaw where a race in page migration caused an incorrect page mapping for the target page, leading to NULL dereferences during dump of page state when memory hotplug/offlining occurs. The root cause was that the target page’s mapping field stor...

CVE-2021-46978

CVE-2021-46978 : Linux kernel KVM nVMX fix for mapping eVMCS after migration. When enlightened VMCS is used and nested state is migrated via vmx_get_nested_state()/vmx_set_nested_state(), evmcs page could not be mapped immediately because evmcs GPA lacked the expected struct kvm_vmx_nested_state_...

CVE-2022-23091

A particular case of memory sharing is mishandled in the virtual memory system. This is very similar to SA-21:08.vm, but with a different root cause. An unprivileged local user process can maintain a mapping of a page after it is freed, allowing that process to read private data belonging to othe...
