CVE-2026-10679

The CVE-2026-10679 issue affects Zephyr’s DesignWare SPI driver (drivers/spi/spi_dw.c). The root cause is that the BAUDR clock divider was computed as info->clock_frequency / config->frequency without validating frequency, allowing a userspace thread with SPI access to pass frequency = 0, t...

CVE-2026-10677 Kernel heap memory leak in `z_vrfy_k_poll()` lets an unprivileged user thread exhaust the kernel resource pool

The CONFIGUSERSPACE syscall verifier zvrfykpoll in kernel/poll.c allocates a kernel-side copy of the user-supplied kpollevent via zthreadmalloc and then validates each event's object handle. Before this fix, validation used KOOPSKSYSCALLOBJ... inline inside the loop, which kills the calling threa...

CVE-2026-10671

CVE-2026-10671 affects Zephyr kernel: the userspace verifier for k_pipe_init used K_SYSCALL_OBJ(), allowing an unprivileged thread with access to a k_pipe object to re-init a live pipe. This re-initialization clears the ring buffer and wait queues without accounting for current blockers, leaving ...

Denial Of Service (DoS)

libvirt.so is vulnerable to denial of serviceDoS attacks. A malicious user is able to cause an application crash via infinite iterations over virNWFilterObj instances because there is no protection to stop an unprivileged thread from concurrently modifying the driver-nwfilters object...
