CVE-2026-46197

The CVE-2026-46197 issue affects the Linux kernel DRM/AMDKFD component, where the nattr field validation for SVM ioctl was insufficient against the reported buffer size, enabling out-of-bounds access via a user-controlled attribute count. The root cause is input size validation failure in the SVM...

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...
