CVE-2026-14986 Out-of-bounds write in it51xxx I2C target FIFO ISR on oversized write transaction

The ITE it51xxx I2C driver, when operating as an I2C target slave in buffer mode CONFIGI2CTARGET + CONFIGI2CTARGETBUFFERMODE, copies host-supplied write data into the fixed-size data-targetinbuffer inside its target FIFO interrupt handler targeti2cisrfifo in drivers/i2c/i2citeit51xxx.c. The copy...

CVE-2026-14986

An out-of-bounds write in the ITE it51xxx I2C driver in Zephyr RTOS (drivers/i2c/i2c_ite_it51xxx.c) occurs when the driver operates as an I2C target in buffer mode. The FIFO interrupt handler target_i2c_isr_fifo() copies host-supplied data into a fixed 256-byte buffer but performs its bounds chec...
