The vulnerability of the sev_dbg_crypt() function in the arch/x86/kvm/svm/sev.c module of the virtualization subsystem on the Linux kernel-based x86 platform allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the sevdbgcrypt function in the arch/x86/kvm/svm/sev.c module of the virtualization subsystem on the Linux kernel-based x86 platform is related to the execution of operations beyond the buffer boundaries in memory. Exploiting this vulnerability could allow an attacker to...

CVE-2026-63794

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM module, specifically within the Secure Virtual Machine SVM component. The sevdbgcrypt function, when handling encryption, incorrectly calculates the transfer length, leading to a page overflow. This memory corruption can resu...

CVE-2026-63794

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Fix page overflow in sevdbgcrypt for ENCRYPT path In sevdbgcrypt, the per-iteration transfer length is bounded by the source page offset PAGESIZE - soff but not by the destination page offset PAGESIZE - doff. When doff...
