CVE-2026-23197 Details
Description
In the Linux kernel, the following vulnerability has been resolved: i2c: imx: preserve error state in block data length handler When a block read returns an invalid length, zero or >I2C_SMBUS_BLOCK_MAX, the length handler sets the state to IMX_I2C_STATE_FAILED. However, i2c_imx_master_isr() unconditionally overwrites this with IMX_I2C_STATE_READ_CONTINUE, causing an endless read loop that overruns buffers and crashes the system. Guard the state transition to preserve error states set by the length handler.
A vulnerability exists in the I2C IMX driver of the Linux kernel, where the error state is not properly preserved during block data length handling. When a block read returns an invalid length, the length handler sets the state to 'IMX_I2C_STATE_FAILED'. However, the interrupt service routine 'i2c_imx_master_isr()' overwrites this state with 'IMX_I2C_STATE_READ_CONTINUE'. This flaw creates an infinite read loop that can overrun buffers and crash the system.
Users can apply the latest patch available in the Linux kernel stable tree to address this vulnerability.
