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...

PT-2026-44270

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description Two issues exist in the vCPU initialization path of the KVM arm64 component. First, a failure occurring after hyp pin shared mem succeeds can lead to a pin leak, where pin references on...
