GHSA-4pq2-jh73-g3hwCVE-2026-53360 0 A vulnerability in the Linux kernel's KVM SEV-SNP implementation allows a malicious SEV-SNP guest to perform out-of-bounds reads and writes on the host kernel heap memory. This occurs due to improper validation of guest-controlled parameters leading to buffer overflows in the GHCB scratch area handling. Exploitation can result in host heap memory corruption and information disclosure. The issue has been resolved by requiring the software scratch area to reside in the GHCB's shared buffer when using GHCB v2+. No affected versions or patch links are explicitly provided.
