linux kernel
vulnerability
mcp251xfd_probe()
dev_err_probe()
devm_clk_get()
oops
In the Linux kernel, the following vulnerability has been resolved: can:
mcp251xfd: mcp251xfd_probe(): fix an error pointer dereference in probe
When we converted this code to use dev_err_probe() we accidentally removed
a return. It means that if devm_clk_get() it will lead to an Oops when we
call clk_get_rate() on the next line.
