In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
HID: sensor: custom: Fix use-after-free in enable_sensor<\/p>\n
enable_sensor_store() can call set_power_report_state(), which
\ndereferences sensor_inst->power_state and sensor_inst->report_state.
\nThese pointers refer to entries in sensor_inst->fields.<\/p>\n
Create the field attributes before exposing the enable_sensor sysfs
\nattribute, so enable_sensor cannot be accessed before the state it
\ndepends on has been initialized.<\/p>\n
On remove, delete enable_sensor before freeing the field attributes,
\nso a concurrent sysfs write cannot dereference freed memory through
\npower_state or report_state.<\/p>\n","protected":false},"excerpt":{"rendered":"
