Description SMASH SMASH 2024-02-29 10:33:05 UTC 
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.
