CVE-2026-18746
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-2026-18746
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-2026-18416
The CoAP link-format helper matchpathuri in subsys/net/lib/coap/coaplinkformat.c compares a registered resource path against the URI carried in a Uri-Query href= option. That URI is not NUL terminated, but the inner character loop advanced its index k once per path character without ever testing ...
