Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Handle protected guests properly in completehypercallexit Use is64bithypercall instead of is64bitmode to detect a 64-bit hypercall when completing said hypercall. For guests with protected state, e.g., SEV-ES and SEV-SN...

CVE-2024-55881

CVE-2024-55881 : In the Linux kernel, KVM for x86 had a fix to correctly detect 64‑bit hypercalls during complete_hypercall_exit() for guests with protected state (e.g., SEV-ES/SEV-SNP). The change replaces is_64_bit_mode() with is_64_bit_hypercall() to determine 64‑bit mode when the vCPU state n...
