zephyr_cve-2021-3625

CVE-2021-3625 This repository contains a few example exploits for CVE-2021-3625. All Zephyr-based usb devices up to and including version 2.5.0 suffer from a buffer overflow allowing readout of up to 65kB. Depending on the actual device this may result of leakage of sensitive data like encryption...

CVE-2026-79977 WireGuard peer endpoint learned from unauthenticated transport-data messages allows off-path tunnel hijack in Zephyr

The WireGuard VPN service in subsys/net/lib/wireguard/wg.c updated the peer endpoint from a message it could not authenticate. In handletransportdata, when the 32-bit receiver index of an incoming transport-data message matched no session, the code both scheduled a new handshake and copied the...

CVE-2026-79977

The WireGuard VPN service in the Zephyr operating system (specifically in subsys/net/lib/wireguard/wg.c) is vulnerable to an off-path tunnel hijack. The handle_transport_data() function incorrectly updates the peer->endpoint by copying the source address of an unauthenticated transport-data me...

CVE-2026-19741

The Zephyr RTOS OpenThread integration is vulnerable because it defines a default Joining Device Credential (PSKd ) of **

CVE-2026-19741 OpenThread joiner autostart uses a publicly documented default Joining Device Credential (PSKd)

Zephyr's OpenThread integration defined CONFIGOPENTHREADJOINERPSKD with default "J01NME" in modules/openthread/Kconfig.thread previously subsys/net/l2/openthread/Kconfig, then subsys/net/l2/openthread/Kconfig.thread. J01NME is the example Joining Device Credential used throughout the public...

CVE-2026-19947

The device multiplexer pseudo-driver in drivers/misc/devmux/devmux.c contains an authorization flaw where the system calls devmux_select_get() and devmux_select_set() bypass kernel-object validation. When CONFIG_USERSPACE and CONFIG_DEVMUX are enabled, user-mode verifiers fail to perform k_object...

CVE-2026-19947 Missing kernel object permission check in devmux syscalls allows unprivileged user threads to retarget a device multiplexer

The device multiplexer pseudo-driver in drivers/misc/devmux/devmux.c exposes two system calls, devmuxselectget and devmuxselectset. When CONFIGUSERSPACE is enabled, their user-mode verifiers zvrfydevmuxselectget and zvrfydevmuxselectset forwarded directly to the kernel implementations without...

CVE-2026-19595 Zephyr RTIO syscall verifier validates output parameters for read instead of write access

The user-mode syscall verifier zvrfyrtiocqegetmempoolbuffer in subsys/rtio/rtiosyscalls.c validated its two output parameters, buff and bufflen, with KSYSCALLMEMORYREAD rather than KSYSCALLMEMORYWRITE. Both are pure out-parameters: zimplrtiocqegetmempoolbuffer stores the mempool buffer address an...

CVE-2026-19595

The Zephyr RTOS contains a vulnerability in the RTIO syscall verifier located in subsys/rtio/rtio_syscalls.c. The function z_vrfy_rtio_cqe_get_mempool_buffer() incorrectly validates the output parameters buff and buff_len using K_SYSCALL_MEMORY_READ() instead of K_SYSCALL_MEMORY_WRITE(). Because ...

CVE-2026-19673 Out-of-bounds read and net_buf length underflow in Zephyr Ethernet L2 when parsing a truncated VLAN header

ethernetrecv in subsys/net/l2/ethernet/ethernet.c validates only that the first netbuf of a received frame holds a plain 14-byte struct netethhdr. When the ethertype is 0x8100 and VLAN is enabled on the interface, the same buffer is reinterpreted as the 18-byte struct netethvlanhdr without...

CVE-2026-19673

The Zephyr RTOS Ethernet L2 layer contains an out-of-bounds read and net_buf length underflow in subsys/net/l2/ethernet/ethernet.c. When parsing a truncated VLAN header (ethertype 0x8100), the ethernet_recv() function fails to re-verify the buffer length when reinterpreting the header as an 18-by...
