NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

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.
