CVE-2026-18416 Out-of-bounds read in CoAP well-known-core Uri-Query href matching (match_path_uri)

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 ...

CVE-2026-18416

The Zephyr RTOS CoAP server subsystem is vulnerable to an out-of-bounds read in the match_path_uri() helper function located in subsys/net/lib/coap/coap_link_format.c. This occurs because the function compares a registered resource path against a Uri-Query href= option without properly checking t...

CVE-2026-18415 Out-of-bounds write in the IEEE 802.15.4 L2 transmit path for oversized non-6LoWPAN frames

ieee802154send in subsys/net/l2/ieee802154/ieee802154.c copies the outgoing packet into a single fixed 125-byte transmit buffer txframebufpool, sized IEEE802154MTU. In builds with CONFIGNETL2IEEE802154FRAGMENT enabled the default whenever CONFIGNET6LO is set, the branch taken when 6LoWPAN...

CVE-2026-18415

The Zephyr RTOS (implied by CONFIG_NET_L2_IEEE802154_FRAGMENT and zsock_socket()) contains an out-of-bounds write vulnerability in the ieee802154_send() function within subsys/net/l2/ieee802154/ieee802154.c. When CONFIG_NET_L2_IEEE802154_FRAGMENT is enabled, the system fails to perform length val...

CVE-2026-18414

The ADI MAX32 ADC driver contains an out-of-bounds write vulnerability due to incorrect buffer size validation in drivers/adc/adc_max32.c. The start_read() function fails to account for sizeof(uint16_t) when comparing the buffer size against the sample count, allowing buffers that are half the re...

CVE-2026-18414 Out-of-bounds write in the ADI MAX32 ADC driver due to incorrect 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-2026-18413

The NXP MCUX LPADC ADC driver is vulnerable to an out-of-bounds write due to a missing buffer size validation in mcux_lpadc_start_read(). The driver fails to verify that the destination buffer is large enough for the requested sampling sequence. In builds with CONFIG_USERSPACE , an unprivileged u...
