golang: internal/syscall/unix: Root.Chmod can follow symlinks out of the root

A flaw was found in the internal/syscall/unix package in the Go standard library. If the target of the Root.Chmod function is replaced with a symbolic link during execution, specifically after Root.Chmod checks the target but before acting, the chmod operation will be performed on the file the...

CVE-2026-10679 Divide-by-zero in DesignWare SPI driver reachable from spi_transceive syscall (local DoS)

The DesignWare SPI driver drivers/spi/spidw.c computed the SPI BAUDR clock divider as info-clockfrequency / config-frequency without validating config-frequency. spitransceive is a Zephyr syscall and its verify handler drivers/spi/spihandlers.c copies the caller-supplied spiconfig from userspace...

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-2026-10674 DoS (hard fault) in NXP LPUART driver: unsupported runtime UART config leaves clocks disabled

The NXP LPUART serial driver drivers/serial/uartmcuxlpuart.c, when CONFIGUARTUSERUNTIMECONFIGURE is enabled, called LPUARTDeinit at the start of mcuxlpuartconfigure, which disables the LPUART peripheral clocks. The requested configuration is validated only afterwards in mcuxlpuartconfigurebasic,...

CVE-2026-10669 Xtensa MPU `arch_buffer_validate()` integer-overflow lets a user thread bypass syscall pointer validation

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...
