CVE-2026-19185 Unvalidated user-supplied buffer pointers in the I3C do_ccc system call handler allow kernel memory read/write from user mode

The system-call verifier for i3cdoccc in drivers/i3c/i3chandlers.c validated the outer struct i3ccccpayload, the broadcast ccc.data buffer and the targets.payloads array, but did not validate the per-target data buffers those array elements point at. Each struct i3cccctargetpayload carries its ow...

EUVD-2026-92285

The NXP GAU ADC driver drivers/adc/adcmcuxgauadc.c validated the caller-supplied sequence-buffersize, which is expressed in bytes, against the number of active channels, which is a sample count. It then stored that byte count directly in data-resultslength and used it in mcuxgauadcreadsamples as...

CVE-2026-19184 Out-of-bounds write in the NXP GAU ADC driver due to byte-versus-sample buffer size validation mismatch

The NXP GAU ADC driver drivers/adc/adcmcuxgauadc.c validated the caller-supplied sequence-buffersize, which is expressed in bytes, against the number of active channels, which is a sample count.

CVE-2026-19184

The NXP GAU ADC driver (drivers/adc/adc_mcux_gau_adc.c) contains an out-of-bounds write vulnerability due to a mismatch between byte-based buffer size validation and sample-count logic. The driver incorrectly treats a byte count as the number of uint16_t slots, allowing a buffer to be overrun by ...
