CVE-2023-53007

Full vulnerability record from the local CVENow database.

Description

In the Linux kernel, the following vulnerability has been resolved: tracing: Make sure trace_printk() can output as soon as it can be used Currently trace_printk() can be used as soon as early_trace_init() is called from start_kernel(). But if a crash happens, and "ftrace_dump_on_oops" is set on the kernel command line, all you get will be: [ 0.456075] <idle>-0 0dN.2. 347519us : Unknown type 6 [ 0.456075] <idle>-0 0dN.2. 353141us : Unknown type 6 [ 0.456075] <idle>-0 0dN.2. 358684us : Unknown type 6 This is because the trace_printk() event (type 6) hasn't been registered yet. That gets done via an early_initcall(), which may be early, but not early enough. Instead of registering the trace_printk() event (and other ftrace events, which are not trace events) via an early_initcall(), have them registered at the same time that trace_printk() can be used. This way, if there is a crash before early_initcall(), then the trace_printk()s will actually be useful.

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: rastreo: Asegúrese de que trace_printk() pueda generar resultados tan pronto como sea posible. Actualmente, trace_printk() puede usarse tan pronto como se llame a early_trace_init() desde start_kernel(). Sin embargo, si se produce un fallo y se configura \"ftrace_dump_on_oops\" en la línea de comandos del kernel, solo se obtendrá: [ 0.456075] -0 0dN.2.347519us : Tipo desconocido 6 [ 0.456075] -0 0dN.2.353141us : Tipo desconocido 6 [ 0.456075] -0 0dN.2.358684us : Tipo desconocido 6. Esto se debe a que el evento trace_printk() (tipo 6) aún no se ha registrado. Esto se realiza mediante una llamada early_initcall(), que puede ser temprana, pero no lo suficiente. En lugar de registrar el evento trace_printk() (y otros eventos ftrace, que no son eventos de seguimiento) mediante una llamada early_initcall(), regístrelos al mismo tiempo que trace_printk(). De esta forma, si se produce un fallo antes de la llamada early_initcall(), las llamadas trace_printk() serán realmente útiles."
