CVE-2026-10647

The CVE concerns the USB CDC-NCM driver (subsys/usb/device_next/class/usbd_cdc_ncm.c) in Zephyr. The code ignores the return value of usbd_ep_enqueue() in cdc_ncm_send(); when enqueue fails, it still calls k_sem_take(&data-sync_sem, K_FOREVER), waiting on a completion that is only signaled from t...

CVE-2026-45195

CVE-2026-45195 affects kernel software inside a Host VM that posts commands to GPU Firmware, enabling memory reads/writes outside the host kernel’s permitted range. Root cause: untrusted addresses passed to rgxfw_set_mips_fault_address in the GPU DDK may grant the firmware privileged memory acces...

CVE-2026-45956

The CVE-2026-45956 entry concerns the Linux kernel DRM Exynos driver (vidi) where vidi_connection_ioctl() incorrectly reads driver_data from drm_dev->dev, which points to the exynos-drm master device rather than the vidi component device. This mismatch can trigger null pointer dereferences, ga...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: uio: uiodmemgenirq: Fixed an issue where the unlock operation was missed in irq configuration. The commit b74351287d4b “uio: fixed a bug in uiodmemgenirqirqcontrol”. corrected the code so that disableirq was called without...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: idpf: Error handling in the inittask during loading was fixed. If the inittask fails during driver loading, we end up with no vports and netdevs, effectively failing the entire process. In that state, a subsequent reset will resu...
