The vulnerability of the mcp_smbus_write() function in the drivers/hid/hid-mcp2221.c module of the user interface subsystem driver for Linux operating systems allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the mcpsmbuswrite function in the drivers/hid/hid-mcp2221.c module of the Linux kernel’s input device subsystem driver relates to the copying of buffers without checking the size of the input data a classic buffer overflow attack. Exploiting this vulnerability could allow an...
