CVE-2024-56787

Estado: ModificadaMedia (5.5)—

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.
