Title
gpio: rockchip: teardown bugs and resource leaks
Summary
In the Linux kernel, the following vulnerability has been resolved: gpio: rockchip: teardown bugs and resource leaks Address several teardown issues and resource leaks in the driver's remove path and error handling: 1. Debounce clock reference leak: The debounce clock (bank->db_clk) is obtained using of_clk_get() which increments the clock's reference count, but clk_put() is never called. Register a devm action to cleanly release it on unbind. Note that of_clk_get(..., 1) remains necessary over devm_clk_get() because the DT binding does not define clock-names, precluding name-based lookup. 2. Unregistered chained IRQ handler: The chained IRQ handler is not disconnected in remove(). If a stray interrupt fires after the driver is removed, the kernel attempts to execute a stale handler, leading to a panic. Fix this by clearing the handler in remove(). 3. IRQ domain leak: The linear IRQ domain and its generic chips are allocated manually during probe but never removed. Remove the IRQ domain during driver teardown to free the associated generic chips and mappings. [Bartosz: don't emit an error message on devres allocation failure]

Debounce clock reference leak: The debounce clock (bank-\u003edb_clk) is\n   obtained using of_clk_get() which increments the clock\u0027s reference\n   count, but clk_put() is never called. Register a devm action to\n   cleanly release it on unbind. Note that of_clk_get(..., 1) remains\n   necessary over devm_clk_get() because the DT binding does not define\n   clock-names, precluding name-based lookup.\n\n2. Unregistered chained IRQ handler: The chained IRQ handler is not\n   disconnected in remove(). If a stray interrupt fires after the driver\n   is removed, the kernel attempts to execute a stale handler, leading\n   to a panic. Fix this by clearing the handler in remove().\n\n3. IRQ domain leak: The linear IRQ domain and its generic chips are\n   allocated manually during probe but never removed. Remove the IRQ\n   domain during driver teardown to free the associated generic chips\n   and mappings.\n\n[Bartosz: don\u0027t emit an error message on devres allocation failure]"

Fuga de referencia del reloj de antirrebote: El reloj de antirrebote (bank -\u003e db_clk) se obtiene usando of_clk_get() lo que incrementa el contador de referencias del reloj, pero clk_put() nunca se llama. Registra una acci\u00f3n devm para liberarlo limpiamente al desvincular. Tenga en cuenta que of_clk_get(..., 1) sigue siendo necesario en lugar de devm_clk_get() porque el enlace DT no define nombres de reloj, lo que impide la b\u00fasqueda basada en nombres.\n\n2. Gestor IRQ encadenado no registrado: El gestor IRQ encadenado no se desconecta en remove(). Si una interrupci\u00f3n errante se dispara despu\u00e9s de que se elimina el controlador, el kernel intenta ejecutar un gestor obsoleto, lo que lleva a un p\u00e1nico. Solucione esto limpiando el gestor en remove().\n\n3. Fuga de dominio IRQ: El dominio IRQ lineal y sus chips gen\u00e9ricos se asignan manualmente durante la sonda pero nunca se eliminan. Elimine el dominio IRQ durante el desmontaje del controlador para liberar los chips gen\u00e9ricos y las asignaciones asociados.\n\n[Bartosz: no emita un mensaje de error en caso de fallo de asignaci\u00f3n de devres]"

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
