The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - KVM: x86: Use trycmpxchguser to update guest PTE A/D bits Use the recently introduced trycmpxchguser to update guest PTE A/D bits instead of mapping the PTE int...
ALPINE-CVE-2024-31145
Certain PCI devices in a system might be assigned Reserved Memory Regions specified via Reserved Memory Region Reporting, "RMRR" for Intel VT-d or Unity Mapping ranges for AMD-Vi. These are typically used for platform tasks such as legacy USB emulation. Since the precise purpose of these regions ...
kernel: KVM: x86: nSVM: fix potential NULL derefernce on nested migration
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...
