In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Stop active perfmon if it is being destroyed If the active performance monitor (`v3d->active_perfmon`) is being destroyed, stop it first. Currently, the active perfmon is not stopped during destruction, leaving the `v3d->active_perfmon` pointer stale. This can lead to undefined behavior and instability. This patch ensures that the active perfmon is stopped before being destroyed, aligning with the behavior introduced in commit 7d1fd3638ee3 ("drm/v3d: Stop the active perfmon before being destroyed").
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/v3d: Detener el monitor de rendimiento activo si se está destruyendo Si se está destruyendo el monitor de rendimiento activo (`v3d->active_perfmon`), deténgalo primero. Actualmente, el monitor de rendimiento activo no se detiene durante la destrucción, lo que deja obsoleto el puntero `v3d->active_perfmon`. Esto puede provocar un comportamiento indefinido e inestabilidad. Este parche garantiza que el monitor de rendimiento activo se detenga antes de destruirse, en consonancia con el comportamiento introducido en el commit 7d1fd3638ee3 ("drm/v3d: Detener el monitor de rendimiento activo antes de destruirse").
