SUSE CVE-2026-64166

In the Linux kernel, the following vulnerability has been resolved: firmware: armffa: Check for NULL FF-A ID table while driver registration The bus match callback assumes that every FF-A driver provides an idtable and dereferences it unconditionally. Enforce that contract at registration time so...

CVE-2026-64081

A flaw was found in the Linux kernel's ARM Firmware Framework for Arm armffa component. This vulnerability arises from insufficient validation of framework notification message layouts. A local attacker, by providing specially crafted firmware data in the shared RX buffer, could trigger an...

CVE-2026-64149

A flaw was found in the Linux kernel's Direct Memory Access DMA mapping subsystem. On ARM64 systems configured with SPARSEMEM a memory management model, the dmamapresource function could incorrectly identify valid memory-mapped input/output MMIO addresses as random access memory RAM. This false...

CVE-2026-64105

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine for ARM64 architecture, specifically within the virtual Generic Interrupt Controller vgic component. When a virtual CPU vCPU fails to initialize, the private Interrupt ReQuests IRQs allocated for it are not properly released...

CVE-2026-64166

A flaw was found in the Linux kernel's ARM FF-A Firmware Framework for Arm firmware. This vulnerability occurs during driver registration, where the bus match callback assumes that every FF-A driver provides an ID table and dereferences it unconditionally. A buggy client driver could exploit this...

CVE-2026-64165

A flaw was found in the Linux kernel, specifically within the ARM Integrator/CP architecture. During early system initialization, a memory allocation function is called before the memory management system is fully ready. This can lead to a kernel crash, resulting in a Denial of Service DoS for th...
