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

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-2026-19737

i2sesp32triggercheck in drivers/i2s/i2sesp32.c validates the requested direction only for I2SDIRBOTH. The I2SDIRRX and I2SDIRTX branches read devcfg-rx.data-configured / devcfg-tx.data-configured without first checking the stream pointers. The device instantiation macro I2SESP32STREAMINIT sets bo...

EUVD-2026-97115

The NXP MCUX TRNG entropy driver in drivers/entropy/entropymcuxtrng.c passed the caller's byte count straight to the vendor SDK routine TRNGGetRandomData. On i.MX RT5xx and RT6xx parts the SDK compiles its TRNGSWHEALTHTESTS variant, which always copies whole 32-bit words and draws entropy rounded...

CVE-2026-19737: NULL Pointer Dereference

i2sesp32triggercheck in drivers/i2s/i2sesp32.c validates the requested direction only for I2SDIRBOTH. The I2SDIRRX and I2SDIRTX branches read devcfg-rx.data-configured / devcfg-tx.data-configured without first checking the stream pointers. The device instantiation macro I2SESP32STREAMINIT sets bo...

i2s esp32 trigger check in drivers/i2s/i2s esp32.c validates the requested direction only for I2S DIR BOTH. The I2S DIR RX and I2S DIR TX branches read dev cfg-rx.data-configured / dev cfg-tx.data-configured without first checking the stream pointers. The device instantiation macro I2S ESP32 STRE...

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-2026-18413 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...

PT-2026-77335

Name of the Vulnerable Software and Affected Versions Zephyr kernel affected versions not specified Description An issue exists in the validation of the k thread join and k thread abort system calls via the thread obj validate function in kernel/thread.c. When k object validate returns an error...

CVE-2026-12364

The user-space system-call verifier zvrfyzlogmsgstaticcreate in subsys/logging/logmsg.c was a pure pass-through: it forwarded the caller-supplied source, desc, package, and data arguments directly to the kernel-mode implementation zimplzlogmsgstaticcreate without performing any of the mandatory...

New PoolParty Process Injection Techniques Outsmart Top EDR Solutions

A new collection of eight process injection techniques, collectively dubbed PoolParty, could be exploited to achieve code execution in Windows systems while evading endpoint detection and response EDR systems. SafeBreach researcher Alon Leviev said the methods are "capable of working across all...
