  3. CVE-2024-46803
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Check debug trap enable before write dbg_ev_file In interrupt context, write dbg_ev_file will be run by work queue. It will cause write dbg_ev_file execution after debug_trap_disable, which will cause NULL pointer access. v2: cancel work "debug_event_workarea" before set dbg_ev_file as NULL.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amdkfd: comprobar la habilitación de la trampa de depuración antes de escribir dbg_ev_file En el contexto de interrupción, la cola de trabajo ejecutará la escritura dbg_ev_file. Esto provocará la ejecución de la escritura dbg_ev_file después de debug_trap_disable, lo que provocará el acceso al puntero NULL. v2: cancelar el trabajo "debug_event_workarea" antes de establecer dbg_ev_file como NULL.
