CVE-2022-49557

CVE-2022-49557 affects the Linux kernel in x86/fpu/KVM. The root cause is KVM’s guest FPU uABI size being set to the host default instead of KVM’s historic size, causing out-of-bounds writes to the XSAVE header when saving FPU state for guests on hosts without XSAVE. This can lead to data corrupt...
