CVE-2026-10669

On Xtensa SoCs built with CONFIGXTENSAMPU and CONFIGUSERSPACE, archbuffervalidate in arch/xtensa/core/mpu.c — the architecture hook that verifies a user-mode-supplied buffer is accessible to the calling user thread with the requested permission — defaulted its return value to 0 access permitted a...

CVE-2026-10669

Summary (CVE-2026-10669) : On Xtensa SoCs with CONFIG_XTENSA_MPU and CONFIG_USERSPACE, arch_buffer_validate() erroneously permits access when the buffer size rounds to a wrap of the 32-bit address space, bypassing MPU checks. This can let an unprivileged user-thread validate or copy memory it sho...

CVE-2026-10667

Zephyr CVE-2026-10667 affects SMP builds with CONFIG_USERSPACE and dynamic objects (CONFIG_DYNAMIC_OBJECTS). The bug is a use-after-free in the dynamic kernel-object tracker: k_object_wordlist_foreach() iterates obj_list under lists_lock while removals and frees occur under objfree_lock/obj_lock,...

CVE-2026-10667 SMP use-after-free in Zephyr `CONFIG_USERSPACE` dynamic kernel-object tracking, reachable from unprivileged user threads

Zephyr's dynamic kernel-object tracking kernel/userspace/userspace.c, formerly kernel/userspace.c maintains a doubly-linked list objlist of dynamically allocated kernel objects. Iteration over this list in kobjectwordlistforeach was performed under listslock using the SAFE iterator which caches t...

CVE-2026-45203

Kernel software installed and running inside a Host VM may post improper commands to the GPU Firmware to trigger a memory write outside the permitted range of memory for the host kernel. A TOCTOU bug existed where a malicious driver could modify values in memory after firmware validation but befo...

CVE-2026-41154

CVE-2026-41154 : The issue affects the GPU DDK in the CMA Cleanup Path of AllocOSPages_Sparse. When indexing pages larger than 4kB in the sparse memory page-freeing logic, an incorrect buffer indexing leads to out-of-bounds (OOB) reads/writes in kernel memory, exposed to software running as a non...

CVE-2026-41154 GPU DDK - Incorrect Index Calculation in CMA Cleanup Path of AllocOSPages_Sparse

Software installed and run as a non-privileged user may cause OOB kernel memory reads or writes through GPU API calls. When indexing pages larger than 4kB in the page freeing logic of the sparse memory implementation, incorrect buffer indexing leads to OOB access...

EUVD-2026-43034

Software installed and run as a non-privileged user may cause OOB kernel memory reads or writes through GPU API calls. When indexing pages larger than 4kB in the page freeing logic of the sparse memory implementation, incorrect buffer indexing leads to OOB access...

The vulnerability of the kvm_set_memory_region() function in the virt/kvm/kvm_main.c module of the KVM virtualization subsystem in the Linux operating system allows a hacker to trigger a service failure.

The vulnerability of the kvmsetmemoryregion function in the virt/kvm/kvmmain.c module of the Kernel-based Virtual Machine KVM virtualization subsystem of the Linux operating system is related to the reutilization of previously released memory. Exploiting this vulnerability could allow an attacker...

kernel: RDMA/vmw_pvrdma: Fix double free on pvrdma_alloc_ucontext() error path

A flaw was found in the Linux kernel, specifically within the RDMA Remote Direct Memory Access vmwpvrdma module. This vulnerability is a double free, which means the system attempts to release the same memory resource twice. This can occur in an error handling path within the pvrdmaallocucontext...

kernel: smb/client: fix out-of-bounds read in smb2_compound_op()

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote attacker, acting as a malicious SMB server, could send a specially crafted, truncated response with an oversized buffer length. This could lead to an out-of-bounds read in the smb2compoundop function, allowing the...

SUSE-SU-2026:22522-1 Security update for the Linux Kernel
