CVE-2026-53141
Description
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.
