CVE-2023-46842

Unlike 32-bit PV guests, HVM guests may switch freely between 64-bit and other modes. This in particular means that they may set registers used to pass 32-bit-mode hypercall arguments to values outside of the range 32-bit code would be able to set them to. When processing of hypercalls takes a...

CVE-2023-46842

CVE-2023-46842 affects the Xen hypervisor. The VULNERABILITY allows HVM guests to switch between 64-bit and other modes, enabling potential manipulation of registers used for 32-bit hypercall arguments. Translation of hypercall arguments and lax sanity checks on register high halves can trigger a...

kernel: x86/sev: Make enc_dec_hypercall() accept a size instead of npages

In the Linux kernel, the following vulnerability has been resolved: x86/sev: Make encdechypercall accept a size instead of npages encdechypercall accepted a page count instead of a size, which forced its callers to round up. As a result, non-page aligned vaddrs caused pages to be spuriously marke...
