In the Linux kernel, the following vulnerability has been resolved:

drm/v3d: Fix global performance monitor reference counting

In the SET_GLOBAL ioctl, v3d_perfmon_find() bumps the reference count on
the perfmon it returns, but v3d_perfmon_set_global_ioctl() and
v3d_perfmon_delete() fail to release that reference on several paths:

1. v3d_perfmon_set_global_ioctl() leaks the reference on its error
paths.

2. CLEAR_GLOBAL leaks both the find reference and the reference
previously stashed in v3d->global_perfmon by the SET_GLOBAL ioctl
that configured it.

3. Destroying a perfmon that is the current global perfmon leaks the
reference stashed by the SET_GLOBAL ioctl.

Release each of these references explicitly.
