Vulnerability from github – Published: 2024-02-28 09:30 – Updated: 2024-12-06 15:31

Details

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.

Severity ?

5.5 (Medium)
