CVE-2026-17053

The Zephyr RTOS SMBus driver API contains a vulnerability where smbus_smbalert_remove_cb() and smbus_host_notify_remove_cb() are exposed as syscalls. These syscalls fail to perform K_SYSCALL_MEMORY_READ/WRITE validation on the caller-supplied struct smbus_callback *cb pointer, forwarding it direc...

CVE-2026-18746

The Zephyr LwM2M client is vulnerable to a NULL pointer dereference in the parse_write_op() function within subsys/net/lib/lwm2m/lwm2m_message_handling.c. When the static CoAP Block1 context pool (defaulting to 3 entries) is exhausted, the init_block_ctx() function returns -ENOMEM and sets the ca...

CVE-2026-18746 NULL pointer dereference in Zephyr LwM2M client when the CoAP Block1 context pool is exhausted

parsewriteop in subsys/net/lib/lwm2m/lwm2mmessagehandling.c handles inbound CoAP WRITE/CREATE requests that carry a Block1 option. For the first block of a transfer it called initblockctx and then immediately stored the peer-selected block size with blockctx-ctx.blocksize = blocksize before...

CVE-2026-18417 Wild pointer dereference in Zephyr BSD sockets when a TCP listening socket reports an asynchronous error

The native BSD-socket layer recorded a pending asynchronous socket error by type-punning it into struct netcontext's void userdata field ctx-userdata = INTTOPOINTER-status in zsockacceptedcb, zsockreceivedcb, zsockconnectedcb and zsockclosectx in subsys/net/lib/sockets/socketsinet.c, reading it...

CVE-2026-18417

The Zephyr RTOS native BSD-socket layer contains a wild pointer dereference vulnerability when a TCP listening socket reports an asynchronous error. The root cause is type-punning an error status into the user_data field of struct net_context. In version v4.3.0 , a second interface-down event can...

CVE-2026-18413 Out-of-bounds write in the NXP MCUX LPADC ADC driver due to missing adc_sequence buffer size validation

The ADC API requires each driver to reject a sampling sequence whose destination buffer is too small: the buffersize field of struct adcsequence in include/zephyr/drivers/adc.h documents that "the driver must ensure that samples are not written beyond the limit and it must return an error if the...

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...
