CVE-2026-46147
CVE-2026-46147 concerns the Linux kernel KVM on ARM64, where two bugs in vCPU initialisation can leak pin references to host vCPU/SVE pages and allow observation of a partially initialised vCPU object. The fixes extract a helper for vCPU registration, ensure proper unpinning on error, and enforce...
