Title
drm/vc4: Stop the active perfmon before being destroyed
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Stop the active perfmon before being destroyed Upon closing the file descriptor, the active performance monitor is not stopped. Although all perfmons are destroyed in `vc4_perfmon_close_file()`, the active performance monitor's pointer (`vc4->active_perfmon`) is still retained. If we open a new file descriptor and submit a few jobs with performance monitors, the driver will attempt to stop the active performance monitor using the stale pointer in `vc4->active_perfmon`. However, this pointer is no longer valid because the previous process has already terminated, and all performance monitors associated with it have been destroyed and freed. To fix this, when the active performance monitor belongs to a given process, explicitly stop it before destroying and freeing it.

Heap reuse of the freed slot is likewise attacker-driven via repeated VC4_PERFMON_CREATE allocations of the same size class.\nPR:L - All required ioctls (VC4_PERFMON_CREATE, VC4_SUBMIT_CL) are marked DRM_RENDER_ALLOW with no capability check, so any unprivileged local user holding the render node \u2014 the default for logged-in desktop users on Raspberry Pi OS and for GPU-passthrough containers/sandboxes on Pi-based edge devices \u2014 can reach it.\nUI:N - The entire sequence is performed by the attacker\u0027s own process; no action by any other user or administrator is needed.\nS:U - The freed object, the stale pointer and all resulting corruption live within the kernel\u0027s own security authority on the affected system; no VM, IOMMU or hypervisor boundary is crossed.\nC:H - A pointer to freed heap memory is retained in device-global state, which per use-after-free scoring gives an attacker-influenced read primitive over reallocated kernel memory. Concretely, when a sprayed perfmon reuses the freed address the start path is skipped so hardware counters are never re-armed, and vc4_perfmon_stop(capture=true) hands the attacker V3D performance-counter values accumulated from other processes\u0027 and the compositor\u0027s GPU workloads via VC4_PERFMON_GET_VALUES.\nI:H - This is a CWE-416 dangling pointer into the kmalloc heap held in a long-lived, cross-process structure, which per use-after-free scoring is treated as High. The stale pointer corrupts driver-global state and another process\u0027s perfmon counter data, and leaves the V3D_PCTRE hardware counter enable register in an attacker-chosen state.\nA:H - The bug drives WARN_ON_ONCE splats in vc4_perfmon_start()/stop() from IRQ context, which is an immediate kernel panic on the panic_on_warn configurations common in hardened and appliance deployments. Even without that, vc4-\u003eactive_perfmon is wedged permanently non-NULL with hardware counters left running, denying the GPU perfmon path to every client until reboot."
