CVE-2026-98720

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine nested virtualization implementation. This flaw allows an attacker within a nested guest to bypass isolation boundaries and directly access host hardware controls, potentially causing host system instability or a Denial of...

CVE-2026-98724

A flaw was found in the Linux kernel's Non-Volatile Memory Express NVMe target PCI endpoint function driver. When processing a Scatter-Gather List SGL segment whose length is shorter than a single descriptor, the system fails to properly validate the segment size. A connected host can exploit thi...

CVE-2026-98707

A flaw was found in the Linux kernel's mac80211 wireless subsystem. A race condition during the teardown of a Receive Block Acknowledgement RX BA session can allow an internal timer to be rearmed after it has been deleted, leaving it queued on freed memory. An attacker within Wi-Fi range could...

CVE-2026-98712

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem for ARM64. The virtual interrupt controller fails to maintain an appropriate reference count on active interrupts, allowing them to be reclaimed and freed while still in use. A malicious guest user could exploit thi...

CVE-2026-98714

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem for AMD processors SVM. When virtual machine execution fails, the hypervisor prematurely updates control fields and marks control blocks as clean, assuming hardware operations were performed. A local attacker could...

CVE-2026-98713

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem for ARM64. A malicious guest user can cause a denial of service DoS on the host system by executing specific instructions on hardware lacking Fine-Grained Traps FGT support. Because trap configurations were improper...

CVE-2026-98717

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem. This vulnerability allows a local user or guest virtual machine to cause a Denial of Service DoS by crashing the host kernel. The issue stems from a race condition between memory slot creation and stage-2 page faul...

CVE-2026-98706

A flaw was found in the Linux kernel's mac80211 wireless subsystem. A local user or adjacent attacker could trigger a Denial of Service DoS resulting in a system crash. This issue arises from a race condition during the removal of an access point AP or mesh station, where background power-save...

CVE-2026-98715

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine AMD Secure Virtual Machine SVM implementation. This flaw can lead to information disclosure or memory corruption due to dropped Translation Lookaside Buffer TLB flushes. When a virtual machine execution VMRUN fails, KVM reset...

CVE-2026-98718

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem supporting AMD SEV Secure Encrypted Virtualization. During virtual machine migration on the same host, CPU cache maintenance was performed after deactivating the source guest's encryption state instead of before. Th...

CVE-2026-98716

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem for AMD processors SVM. During nested virtualization, KVM incorrectly checked whether Model-Specific Register MSR accesses were intercepted by referencing the wrong control structure's permission bitmap. A malicious...
