  "details": "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-\u003evalue[] 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.",
