  3. CVE-2024-56787
In the Linux kernel, the following vulnerability has been resolved: soc: imx8m: Probe the SoC driver as platform driver With driver_async_probe=* on kernel command line, the following trace is produced because on i.MX8M Plus hardware because the soc-imx8m.c driver calls of_clk_get_by_name() which returns -EPROBE_DEFER because the clock driver is not yet probed. This was not detected during regular testing without driver_async_probe. Convert the SoC code to platform driver and instantiate a platform device in its current device_initcall() to probe the platform driver. Rework .soc_revision callback to always return valid error code and return SoC revision via parameter. This way, if anything in the .soc_revision callback return -EPROBE_DEFER, it gets propagated to .probe and the .probe will get retried later.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: soc: imx8m: Sondear el controlador SoC como controlador de plataforma Con driver_async_probe=* en la línea de comandos del kernel, se produce el siguiente seguimiento porque en el hardware i.MX8M Plus, el controlador soc-imx8m.c llama a of_clk_get_by_name(), que devuelve -EPROBE_DEFER porque el controlador de reloj aún no se ha sondeado. Esto no se detectó durante las pruebas regulares sin driver_async_probe. Convierta el código SoC en controlador de plataforma e instancie un dispositivo de plataforma en su device_initcall() actual para sondear el controlador de plataforma. Reelabore la devolución de llamada .soc_revision para que siempre devuelva un código de error válido y devuelva la revisión de SoC mediante un parámetro. De esta manera, si algo en la devolución de llamada .soc_revision devuelve -EPROBE_DEFER, se propaga a .probe y .probe se volverá a intentar más tarde.
