"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ch9200: fix uninitialised access during mii_nway_restart\n\nIn mii_nway_restart() the code attempts to call\nmii->mdio_read which is ch9200_mdio_read(). ch9200_mdio_read()\nutilises a local buffer called \"buff\", which is initialised\nwith control_read(). However \"buff\" is conditionally\ninitialised inside control_read():\n\n if (err == size) {\n memcpy(data, buf, size);\n }\n\nIf the condition of \"err == size\" is not met, then\n\"buff\" remains uninitialised. Once this happens the\nuninitialised \"buff\" is accessed and returned during\nch9200_mdio_read():\n\n return (buff[0] | buff[1] << 8);\n\nThe problem stems from the fact that ch9200_mdio_read()\nignores the return value of control_read(), leading to\nuinit-access of \"buff\".\n\nTo fix this we should check the return value of\ncontrol_read() and return early on error."
