CVE-2026-89924

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine component for s390 architecture. When handling guest debug requests, a memory leak occurs if a watchpoint import fails. A local guest user could repeatedly trigger this flaw, leading to a continuous leak of memory buffers. Th...

CVE-2026-89923

A flaw was found in KVM s390. A memory leak occurs in the Kernel-based Virtual Machine KVM for s390 architecture when a virtual CPU vCPU is destroyed while hardware breakpoints are still active, as the associated debug data is not properly freed. A local attacker or a malicious guest operating...

CVE-2026-89909

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for LoongArch architecture. During initialization, if a specific setup function fails, critical resources are not properly released. This can lead to a resource leak, potentially allowing a local attacker to cause a denial of...

kernel: KVM: s390: vsie: zero stale crypto bits

A flaw was found in the Linux kernel's KVM s390 Virtual Shared Inter-Partition Emulation VSIE component. When shadowing crypto access bits from a format0 apcb, stale crypto bits were not properly cleared. This oversight could allow a nested guest to potentially access a device that should no long...

kernel: KVM: SVM: Fix page overflow in sev_dbg_crypt() for ENCRYPT path

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...

kernel: KVM: SVM: Update x2APIC MSR intercepts if AVIC is inhibited while L2 is active

A flaw was found in KVM Kernel-based Virtual Machine. When the Advanced Virtual Interrupt Controller AVIC is inhibited while a nested guest L2 is active, KVM fails to properly update x2APIC MSR intercepts for the primary guest L1. This allows the L1 guest to read the host's APIC state, send...
