Description


In the Linux kernel, the following vulnerability has been resolved: i2c/designware: Fix an initialization issue The i2c_dw_xfer_init() function requires msgs and msg_write_idx from the dev context to be initialized. amd_i2c_dw_xfer_quirk() inits msgs and msgs_num, but not msg_write_idx. This could allow an out of bounds access (of msgs). Initialize msg_write_idx before calling i2c_dw_xfer_init().
