Description
Description
In the Linux kernel, the following vulnerability has been resolved:
HID: haptic: don't write an uninitialized value to unhandled usages
fill_effect_buf() initializes value only for the four haptic usages
handled by its switch, but writes it to field->value[] for every usage.
An unhandled usage can therefore receive either an uninitialized value
or one left over from the previous usage. hid_output_report() then
serializes that value into the effect's report buffer.
Skip unhandled usages instead. This also matches switch_mode(), which
only updates fields it recognizes.
Found with Clang's -Wconditional-uninitialized.
