  "description": "In the Linux kernel, the following vulnerability has been resolved:  i2c: imx: fix locked bus on SMBus block-read of 0 (IRQ)  SMBus 3.1 6.5.7 allows a Block Read byte count of 0, but the interrupt-driven block-read state machine rejects it as -EPROTO. Worse, it returns without a NACK\u002BSTOP: the next receive cycle has already started, so the target keeps holding SDA and the bus stays stuck until a power cycle of this i2c controller.  Accept count=0: NACK the in-flight dummy byte (TXAK) and set msg-\u003Elen to 2 so i2c_imx_isr_read_continue() emits STOP via its normal last-byte path. The dummy byte is discarded; block-read callers only consume buf[0..count-1].  Reading I2DR has likewise already armed the next byte on the count \u003E I2C_SMBUS_BLOCK_MAX error path, so NACK it (TXAK) before aborting with -EPROTO; otherwise the failing transfer\u0027s STOP cannot complete and the bus stays held.  The atomic path regressed earlier (v3.16) and is fixed separately; this patch covers only the v6.13 state-machine rework.",
